TS27L2C,I,M PRECISION VERY LOW POWER CMOS DUAL OPERATIONAL AMPLIFIERS n VERY LOW POWER CONSUMPTION : 10µA/op n OUTPUT VOLTAGE CAN SWING TO GROUND n EXCELLENT PHASE MARGIN ON CAPACITIVE LOADS N n DIP8 STABLE AND LOW OFFSET VOLTAGE (Plastic Package) n THREE INPUT OFFSET VOLTAGE SELECTIONS DESCRIPTION D These devices are low cost, low power dual oper- SO8 (Plastic Micropackage) ational amplifiers designed to operate with single or dual supplies. These operational amplifiers use the ST silicon gate CMOS process allowing an ex- cellent 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) q I = 10µA/amp.: TS27L2 (very low power) CC q PIN CONNECTIONS (top view) I = 150µA/amp.: TS27M2 (low power) CC q I = 1mA/amp.: TS272 (standard) CC These CMOS amplifiers offer very high input im- pedance and extremely low input currents. The 1 8 major advantage versus JFET devices is the very low input currents drift with temperature (see fig- 2 - 7 ure 2). 3 + - 6 ORDER CODE 4 + 5 Package Part Number Temperature Range N D P 1 - Output 1 TS27L2C/AC/BC 0°C, +70°C • • • 2 - Inverting Input 1 3 - Non-inverting Input 1 TS27L2I/AI/BI -40°C, +125°C • • • 4 - V - TS27L2M/AM/BM -55°C, +125°C • • • 5 - NoCnC-inverting Input 2 Example : TS27L2ACN 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 1/9
