TS272ACDT STMicroelectronics

TS272C,I,M HIGH PERFORMANCE CMOS DUAL OPERATIONAL AMPLIFIERS OUTPUT VOLTAGE CAN SWING TO GROUND EXCELLENT PHASE MARGIN ON CAPACITIVE LOADS GAIN BANDWIDTH PRODUCT: 3.5MHz N STABLE AND LOW OFFSET VOLTAGE DIP8 (Plastic Package) THREE INPUT OFFSET VOLTAGE SELECTIONS DESCRIPTION D The TS272 devices are low cost, dual operational SO8 amplifiers designed to operate with single or dual (Plastic Micropackage) supplies. These operational amplifiers use the ST silicon gate CMOS process allowing an excellent consumption-speed ratio. These series are ideally suited for low consumption applications. P Three power consumptions are available allowing TSSOP8 to have always the best consumption-speed ratio: (Thin Shrink Small Outline Package) I = 10A/amp.: TS27L2 (very low power) CC PIN CONNECTIONS (top view) I = 150A/amp.: TS27M2 (low power) CC I = 1mA/amp.: TS272 (standard) CC These CMOS amplifiers offer very high input im- 1 8 pedance and extremely low input currents. The major advantage versus JFET devices is the very 2 7 - low input currents drift with temperature (see fig- ure 2). + 3 6 - ORDER CODE + 45 Package Part Number Temperature Range ND P 1 - Output 1 2 - Inverting Input 1 TS272C/AC/BC 0C, +70C 3 - Non-inverting Input 1 TS272I/AI/BI -40C, +125C - 4 - V CC TS272M/AM/BM -55C, +125C 5 - Non-inverting Input 2 Example : TS272ACN 6 - Inverting Input 2 7 - Output 2 + 8 - V N = Dual in Line Package (DIP) CC D = Small Outline Package (SO) - also available in Tape & Reel (DT) P = Thin Shrink Small Outline Package (TSSOP) - only available in Tape & Reel (PT) November 2001 1/9TS272C,I,M BLOCK DIAGRAM V CC Current x I Output Input source Second stage differential Output stage V CC E E ABSOLUTE MAXIMUM RATINGS Symbol Parameter TS272C/AC/BC TS272I/AI/BI TS272M/AM/BM Unit + 1) V 18 V Supply Voltage CC 2) V 18 V id Differential Input Voltage 3) V -0.3 to 18 V Input Voltage i + I Output Current for V 15V 30 mA o CC I Input Current 5 mA in T Operating Free-Air Temperature Range 0 to +70 -40 to +125 -55 to +125 C oper T Storage Temperature Range -65 to +150 C stg 1. All values, except differential voltage are with respect to network ground terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. 3. The magnitude of the input and the output voltages must never exceed the magnitude of the positive supply voltage.
