Low Power Dual Operational Amplifiers

DESCRIPTION

These devices consist of two independent, high gain, internally frequency-compensated operational amplifiers designed operate from a single supply over a wide range of voltages. Operation from split supplies also is possible if the difference between the two supplies is 3V to 32V, and Vcc is at least 1.5V more positive than the input common-mode voltage, the low supply-current drain is independent of the magnitude of the power supply voltage.

APPLICATIONS

 Electronic products  Power supply  Remote controller  Consuming products

FEATURES

 Two internally compensated OP amps  Internally frequency compensated for unity gain  Short circuit protection  Wide power supply range: 3V DC to 32V DC (Single supply)  Input common-mode voltage range includes ground  Large output voltage swing: 0V DC to Vcc-1.5VDC BLOCK DIAGRAM Q2 Q3 Q1 Q4 Q9Q8 Cc Q11 Q12 Rsc Non Inverting Output 6uA 50uA Q13 100uA6uA Vcc Q10Input Inverting Input
