description
The TLV245x is a family of rail-to-rail input/output operational amplifiers that sets a new performance point for supply current and ac performance. These devices consume a mere 23 A/channel while offering 220 kHz of gain-bandwidth product, much higher than competitive devices with similar supply current levels. Along with increased ac performance, the amplifier provides high output drive capability, solving a major shortcoming of older micropower rail-to-rail input/output operational amplifiers. The TLV245x can swing to within 250 mV of each supply rail while driving a 2.5-mA load. Both the inputs and outputs swing rail-to-rail for increased dynamic range in low-voltage applications. This performance makes the TLV245x family ideal for portable medical equipment, patient monitoring systems, and data acquisition circuits.

description (continued)
Three members of the family (TLV2450/3/5) offer a shutdown terminal for conserving battery life in portable applications. During shutdown, the outputs are placed in a high-impedance state and the amplifier consumes only 16 nA/channel. The family is fully specified at 3 V and 5 V across an expanded industrial temperature range (- 40C to 125C). The singles and duals are available in the SOT23 and MSOP packages, while the quads are available in TSSOP. The TLV2450 offers an amplifier with shutdown functionality all in a 6-pin SOT23 package, making it perfect for high density circuits.

APPLICATION INFORMATION shutdown function
Three members of the TLV245x family (TLV2450/3/5) have a shutdown terminal for conserving battery life in portable applications. When the shutdown terminal is pulled low, the supply current is reduced to 16 nA/channel, the amplifier is disabled, and the outputs are placed in a high impedance mode. To enable the amplifier, the shutdown terminal must be pulled high. The shutdown terminal should never be left floating. The shutdown terminal threshold is always referenced to the ground terminal of the device. Therefore, when operating the device with split supply voltages (e.g. 2.5 V), the shutdown terminal needs to be pulled to VDD- (not GND) to disable the operational amplifier. The amplifier's output with a shutdown pulse is shown in Figures 42, 43, 44, and 45. The amplifier is powered with a single 5-V supply and configured as a noninverting configuration with a gain of 5. The amplifier turnon and turnoff times are measured from the 50% point of the shutdown pulse to the 50% point of the output waveform. The times for the single, dual, and quad are listed in the data tables. Figures 46 and 47 show the amplifier's forward and reverse isolation in shutdown. The operational amplifier is powered by 1.35-V supplies and configured as a voltage follower (AV = 1). The isolation performance is plotted across frequency using 0.1-VPP, 1.5-VPP, and 2.5-VPP input signals. During normal operation, the amplifier would not be able to handle a 2.5-VPP input signal with a supply voltage of 1.35 V since it exceeds the common-mode input voltage range (VICR). However, this curve illustrates that the amplifier remains in shutdown even under a worst case scenario.
driving a capacitive load
When the amplifier is configured in this manner, capacitive loading directly on the output will decrease the device's phase margin leading to high frequency ringing or oscillations. Therefore, for capacitive loads of greater than 10 pF, it is recommended that a resistor be placed in series (RNULL) with the output of the amplifier, as shown in Figure 49. A minimum value of 20 should work well for most applications.

APPLICATION INFORMATION offset voltage
The output offset voltage, (VOO) is the sum of the input offset voltage (VIO) and both input bias currents (IIB) times the corresponding gains. The following schematic and formula can be used to calculate the output offset voltage:

general configurations
When receiving low-level signals, limiting the bandwidth of the incoming signals into the system is often required. The simplest way to accomplish this is to place an RC filter at the noninverting terminal of the amplifer (see Figure 51).

Figure 51. Single-Pole Low-Pass Filter If even more attenuation is needed, a multiple pole filter is required. The Sallen-Key filter can be used for this task. For best results, the amplifier should have a bandwidth that is 8 to 10 times the filter frequency bandwidth. Failure to do this can result in phase shift of the amplifier.

APPLICATION INFORMATION macromodel information
Macromodel information provided was derived using Microsim PartsTM, the model generation software used with Microsim PSpiceTM. The Boyle macromodel (see Note 1) and subcircuit in Figure 54 are generated using the TLV245x typical electrical and operating characteristics at TA = 25C. Using this information, output simulations of the following key parameters can be generated to a tolerance of 20% (in most cases):
D D D D D D
Maximum positive output voltage swing Maximum negative output voltage swing Slew rate Quiescent power dissipation Input bias current Open-loop voltage amplification
D D D D D D
Unity-gain frequency Common-mode rejection ratio Phase margin DC output resistance AC output resistance Short-circuit output current limit
