General Description

G1211 is a input/output rail-to-rail Operational Amplifier. It can be operated from +2.2V to +5.5V single supply or from ±1.1V to ±2.75 dual supply. G1211 can drive 66mA into resistor loads to within 10 power rail. AC performance is very excellent with 6.5MHz bandwidth, 6.5V/µs Slew Rate, 95dB open loop gain, 60 degree phase margin and low distortion.
