| (R) TS942 3V OUTPUT RAIL TO RAIL MICROPOWER DUAL BiCMOS OPERATIONAL AMPLIFIERS . . . . . . MICROPOWER CONSUMPTION : 1.2A/operator RAIL TO RAIL OUTPUT VOLTAGE RANGE SINGLE SUPPLY OPERATION FROM 2.6V TO 10V EXTREMELY LOW INPUT BIAS CURRENT : 1pA typ. ESD TOLERANCE : 2kV LATCH UP IMMUNITY N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) DESCRIPTION The TS942 is an output RAIL TO RAIL dual BiCMOS operational amplifier offering an extremely low consumption of 1.2A/op. This current is stable over the single supply operating range 2.6V to 10V. The output reaches : t VCC- +150mV VCC+ -150mV with RL = 10k This device is particularly well suited for battery supplied systems (alarm, smoke detector, battery charge control, pH meter...).

All voltage 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 input and output voltages must never exceed VCC+ +0.3V.
