Output C General Description TS324/TS2902 contains four independent high gain operational amplifiers with internal frequency compensation. The four op-amps use a split power supply. The device has low power supply current drain, regardless or the power supply voltage. The low power drain also makes the TS324/TS2902 a good choice for battery operation. When your project calls for a traditional op-amp function, now you can streamline your design with a simple single power supply. Use ordinary +5V common to practically any digital system or personal computer application, without requiring an extra 15V power supply just to have the interface electronics you need. TS324/TS2902 is a versatile, rugged workhorse with a thousand-and-one uses, from amplifying signals from a variety of transducers to dc gain blocks, or any op-amp function. The attached pages offer some recipes that will have your project cooking in no time. Features Single supply operation: 3V to 32V Low input bias currents Internally compensated Common mode range extends to negative supply Single and split supply operation Block Diagram Ordering Information Part No. TS324CD14 C4 TS324CS14 RL TS2902CD14 C4 TS2902CS14 RL Package DIP-14 SOP-14 DIP-14 SOP-14 Packing 50pcs / Tube 2.5Kpcs / 13" Reel 50pcs / Tube 2.5Kpcs / 13" Reel Absolute Maximum Rating Parameter Supply Voltage TS324 TS2902 TS324 TS2902 Symbol VCC Limit Unit +32 or 16 V +26 or 13 Differential Input Voltage 32 VIDR V (Split Power Supplies) 26 -0.3 to 32 Input Common Mode Voltage Range (note 1) VICR V -0.3 to 26 Input Forward Current (note 2) IIF 50 mA Output Short Circuit Duration tsc Continuous TS324 0 ~ +70 o Operating Temperature Range TOPR C TS2902 -40 ~ +85 o Junction Temperature TJ +150 C o Storage Temperature Range TSTG -65 ~ +150 C Note 1: For supply. Voltages less than 32V/26V for the TS324/TS2902 the absolute maximum input voltage is equal to the supply voltage. Note 2: This input current will only exist when the voltage is negative at any of the input leads. Normal output states will reestablish when the input voltage returns to a voltage greater than -0.3V. 1/8 Version: A07 TS324/TS2902 Low Power Quad Operational Amplifiers Electrical Characteristics (Vcc = 5V, Ta=25 C; unless otherwise specified.) o Characteristics Symbol TS324 Min Typ Max Min TS2902 Typ Max Unit Input Offset Voltage VCC= 5.0V to 30V, VIC= 0V to Vcc -1.7 V, -2.0 7.0 -2.0 7.0 mV Vo= 1.4V, RS= 0 Vio --9.0 --10 TLOW Ta THIGH Average Temperature Coefficient of Input o Iio/T -7.0 --7.0 -uV/ C Offset Voltage Input Offset Current -5.0 50 -5.0 50 Iio nA TLOW Ta THIGH --150 --200 Average Temperature Coefficient of input o Iio/T -10 --10 -pA/ C Offset Current Input Bias Current --90 -250 --90 -250 IIB nA TLOW Ta THIGH ---500 ---500 Input Common-Mode Voltage Range VCC = 30 V (Note1) VICR 0 -28.3 0 -24.3 V VCC = 30 V, TLOW Ta THIGH 0 -28 0 -24 Differential Input Voltage Range VIDR --VCC --VCC V Large Signal Open-Loop Voltage Gain RL = 2.0K, VCC =15V, For Large VO Swing, AVOL 25 100 -25 100 -V/mV TLOW Ta THIGH 15 --15 --Channel Separation ---120 ---120 -dB 1.0 KHz to 20KHz Common Mode Rejection Ratio CMRR 65 70 -50 70 -dB RS 10 k Power Supply Rejection Ratio PSRR 65 100 -50 100 -dB Output Voltage -- High Limit VOH V VCC = 30 V, RL = 2 k 26 --22 --VCC = 30 V, RL = 10 k 27 28 -23 24 -Output Voltage -- Low Limit VOL -5.0 20 -5.0 100 mV VCC = 5.0 V, RL = 10 k Output Source Current IO+ 20 40 -20 40 -mA VID=+1.0V,VCC=15V Output Sink Current VID = -1.0 V, VCC = 15 V IO10 20 -10 20 -mA VID = -1.0 V, VO = 200 mV 12 50 -12 50 -uA Output Short Circuit to Ground (Note 2) IOS -40 60 -40 60 mA Power Supply Current VCC = 30 VVO = 0 V, RL = ICC -1.5 3.0 -1.5 3.0 mA VCC = 5.0 V, VO = 0 V, RL = -0.7 1.2 -0.7 1.2 Notes 1: The input common mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end of the common mode voltage range is Vcc 17V, but either or both inputs can go to +32V. Note 2: Short circuits from the output to Vcc can cause excessive heating and eventual destruction. Destructive dissipation can recruit from simultaneous shorts on all amplifiers. 2/8 Version: A07 TS324/TS2902 Low Power Quad Operational Amplifiers Electrical Characteristics Curve Figure 1.

Power Supply Current vs. Supply Voltage 3/8 Version: A07 TS324/TS2902 Low Power Quad Operational Amplifiers Application Description The TS324/TS2902 made using four internally compensated, two-stage operational amplifiers. The first stage performs not only the first stage gain function but also performs the level shifting and transconductance reduction functions. By reducing the transconductance, a smaller compensation capacitor (only 5.0pF) can be employed, thus saving chip area. Another feature of this input stage is that the input common mode range can include the negative supply or ground, in single supply operation, without saturating either the input devices or the differential to singleended converter. The second stage consists of a standard current source load amplifier stage. Each amplifier is biased from an internal-voltage regulator, and which has a low temperature coefficient thus giving each amplifier good temperature characteristics as well as excellent power supply rejection.
