TFA9843AJ 20 W stereo power amplifier with volume control Rev. 01 -- 28 April 2006 Preliminary data sheet 1. General description The TFA9843AJ contains two identical audio power amplifiers. The TFA9843AJ can be used as two Single-Ended (SE) channels with a volume control. The maximum gain is 26 dB. The TFA9843AJ comes in a 9-pin DIL-bent-SIL (DBS9P) power package. The TFA9843AJ is pin compatible with the TFA9842AJ, TFA9843(B)J, TFA9842(B)J and TFA9841J. The difference between the TFA9843AJ and the TFA9843(B)J, TFA9842(B)J, TFA9841J is the functionality of pin 7. The TFA9843AJ has a volume control on pin 7 (VC). The TFA9843(B)J, TFA9842(B)J and TFA9841J have a mode select on pin 7 (MODE). The TFA9843AJ contains a unique protection circuit that is solely based on multiple temperature measurements inside the chip. This gives maximum output power for all supply voltages and load conditions with no unnecessary audio holes. Almost any supply voltage and load impedance combination can be made as long as thermal boundary conditions (number of channels used, external heatsink and ambient temperature) allow it. 2.

Functional description 8.1 Input configuration The input cut-off frequency is as follows: 1 f i ( -3dB ) = ---------------------------2 ( R i x C i ) (1) Single-ended application: Ri = 60 k and Ci = 220 nF: 1 f i ( -3dB ) = ---------------------------------------------------------------- = 12 Hz 3 -9 2 ( 60 x 10 x 220 x 10 ) (2) As shown in Equation 2, large capacitor values for the inputs are not necessary; therefore switch-on delay during charging of the input capacitors can be minimized. This results in a good low frequency response and good switch-on behavior. The TFA9843AJ has clamps on the inputs. In Standby mode the voltage on the input pins is clamped for voltages lower than -0.1 V. When the TFA9843AJ is in Mute, Volume control or Operating mode (maximum gain) the input clamp voltage is 1 V (RMS). 8.2 Power amplifier The power amplifier is a single-ended amplifier with an all NPN output stage, capable of delivering a peak output current of 4 A. 8.2.1 Output power measurement The output power as a function of the supply voltage is measured on the output pins at THD = 10 %; see Figure 7. The maximum output power is limited by the supply voltage of 26 V and the maximum available output current is 4 A repetitive peak current. A minimum load of 3 is required for supply voltages > 22 V; see Figure 4. The output power is measured with one channel driven. TFA9843AJ_1 (c) Koninklijke Philips Electronics N.V. 2006.

At VCC = 18 V and Po = 6.5 W (SE with RL = 4 ) at THD < 0.5 % (see Figure 5), the Average Listening Level (ALL) music power without any distortion yields: 6.5 P o ( ALL, SE ) = ------------ = 410 mW 15.85 (3) The power dissipation can be derived from Figure 8 (SE) for 0 dB respectively 12 dB headroom; see Table 4. For the average listening level a power dissipation of 4.2 W can be used for a heatsink calculation. Table 4.

Table 5. VI(VC) 0 V to 0.8 V Mode selection Status Standby Definition 1.2 V to 1.5 V Mute 1.5 V to 5.0 V Volume control 5.0 V to VCC On (maximum gain) in this mode the current consumption is very low and the outputs are floating; the device is in Standby mode when VI(VC) < 0.8 V in this mode the amplifier is DC-biased but not operational (no audio output); this allows the input coupling capacitors to be charged to avoid plop noise; the device is in Mute mode when 1.2 V < VI(VC) < 1.5 V in this mode the volume of the amplifier can be controlled; the gain can be adjusted between the range of 1.5 V < VI(VC) < 5.0 V in this mode the amplifier has its maximum gain; the Operating mode is activated at VI(VC) > 5.0 V 8.4 Supply voltage ripple rejection The supply voltage ripple rejection (SVRR) is measured with an electrolytic capacitor of 150 F connected to pin SVR with a bandwidth of 20 Hz to 22 kHz. The SVRR as a function of the frequency is illustrated in Figure 10. A larger capacitor value on pin SVR improves the ripple rejection behavior at the lower frequencies.

Preliminary data sheet Rev. 01 -- 28 April 2006 5 of 19 Philips Semiconductors TFA9843AJ 20 W stereo power amplifier with volume control 8.5 Built-in protection circuits The TFA9843AJ contains two types of temperature sensors; one measures the local temperatures of the power stages and one measures the global chip temperature. At a local temperature of the power stage of approximately 185 C or a global temperature of approximately 150 C this detection circuit switches off the power stages for 2 ms. When the outputs are switched off the voltage is measured on the outputs. In the event of a short-circuit to ground or to VCC the device will remain in Protection mode. In all other cases the power stages switch-on automatically and the detection will take place again; however a too high temperature will switch-off the power stages immediately. This can result in repetitive switching during too high junction temperature. This protects the TFA9843AJ against short-circuits to ground, to the supply voltage, across the load and too high chip temperatures. The protection will only be activated when necessary, so even during a short-circuit condition, a certain amount of (pulsed) current will still flow through the short-circuit (as much as the power stage can handle without exceeding the critical temperature level). 9.

The input reference grounds have to be tied with their respective source grounds and must have separate tracks from the power ground tracks; this will prevent the large output signal currents from interfering with the small AC input signals. The small-signal ground tracks should be physically located as far as possible from the power ground tracks. Supply and output tracks should be as wide as possible for delivering maximum output power. AUDIO POWER CS NIJMEGEN PF / 3002 .naJ 72 TVA TFA9843J CIV 22 F MODE Fig 15. Printed-circuit board layout (single-sided); components view 13.2.2 Power supply decoupling Proper supply bypassing is critical for low-noise performance and high supply voltage ripple rejection. The respective capacitor location should be as close as possible to the device and connected to the power ground. Proper power supply decoupling also prevents unwanted oscillations. For suppressing higher frequency transients (spikes) on the supply rail a capacitor with low ESR (typical 100 nF) has to be placed as close as possible to the device. For suppressing lower frequency noise and ripple signals, a large electrolytic capacitor (e.g. 1000 F or greater) must be placed close to the device. The bypass capacitor connected to pin SVR reduces the noise and ripple on the mid rail voltage. For good THD and noise performance, a low ESR capacitor is recommended.

Preliminary data sheet Rev. 01 -- 28 April 2006 12 of 19 Philips Semiconductors TFA9843AJ 20 W stereo power amplifier with volume control 13.3 Thermal behavior and heatsink calculation The measured maximum thermal resistance of the IC package, Rth(j-mb), is 2.0 K/W. A calculation for the heatsink can be made, with the following parameters: Tamb(max) = 60 C (example) VCC = 18 V and RL = 4 (SE) Tj(max) = 150 C (specification) Rth(tot) is the total thermal resistance between the junction and the ambient including the heatsink. This can be calculated using the maximum temperature increase divided by the power dissipation: Rth(tot) = (Tj(max) - Tamb(max))/P At VCC = 18 V and RL = 4 (2 x SE) the measured worst case sine wave dissipation is 8.4 W; see Figure 8. For Tj(max) = 150 C the temperature raise, caused by the power dissipation, is: 150 - 60 = 90 C: P x Rth(tot) = 90 C Rth(tot) = 90/8.4 K/W = 10.7 K/W Rth(h-a) = Rth(tot) - Rth(j-mb) = 10.7 K/W - 2.0 K/W = 8.7 K/W This calculation is for an application at worst case (stereo) sine wave output signals. In practice music signals will be applied, which decreases the maximum power dissipation to approximately half of the sine wave power dissipation; see Section 8.2.2. This allows the use of a smaller heatsink: P x Rth(tot) = 90 C Rth(tot) = 90/4.2 K/W = 21.4 K/W Rth(h-a) = Rth(tot) - Rth(j-mb) = 21.4 K/W - 2.0 K/W = 19.4 K/W TFA9843AJ_1 (c) Koninklijke Philips Electronics N.V. 2006.

Soldering 16.1 Introduction to soldering through-hole mount packages This text gives a brief insight to wave, dip and manual soldering. A more in-depth account of soldering ICs can be found in our Data Handbook IC26; Integrated Circuit Packages (document order number 9398 652 90011). Wave soldering is the preferred method for mounting of through-hole mount IC packages on a printed-circuit board. 16.2 Soldering by dipping or by solder wave Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. Typical dwell time of the leads in the wave ranges from 3 seconds to 4 seconds at 250 C or 265 C, depending on solder material applied, SnPb or Pb-free respectively. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg(max)). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. 16.3 Manual soldering Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 C and 400 C, contact may be up to 5 seconds. 16.4 Package related soldering information Table 10.

For PMFP packages hot bar soldering or manual soldering is suitable. TFA9843AJ_1 (c) Koninklijke Philips Electronics N.V. 2006. All rights reserved.
