TS27L2C,I,M PRECISION VERY LOW POWER CMOS DUAL OPERATIONAL AMPLIFIERS s VERY LOW POWER CONSUMPTION : 10µA/op s OUTPUT VOLTAGE CAN SWING TO GROUND s EXCELLENT PHASE MARGIN ON CAPACITIVE LOADS s STABLE AND LOW OFFSET VOLTAGE s THREE INPUT OFFSET VOLTAGE SELECTIONS DESCRIPTION These devices are low cost, low power dual operational amplifiers designed to operate with single or dual 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. Three power consumptions are available allowing to have always the best consumption-speed ratio: N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) P TSSOP8 (Thin Shrink Small Outline Package) u ICC = 10µA/amp.: TS27L2 (very low power) u ICC = 150µA/amp.: TS27M2 (low power) u ICC = 1mA/amp.: TS272 (standard) These CMOS amplifiers offer very high input impedance and extremely low input currents. The major advantage versus JFET devices is the very low input currents drift with temperature (see figure 2).

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.
