General Description

G1214A is a input/output rail-to-rail Operational Amplifier. It can be operated from +2.2V to +7V single supply or from ±1.1V to ±3.5 dual supply. G1214A can drive 66mA into resistor loads to within 10 power rail. AC performance is very excellent with 6.5MHz band width, 6.5V/µs Slew Rate, 95dB open loop gain, 60 degree phase margin and low distortion.

Supply current of G1214A is only 500µA per Amplifier. It is very suitable for low current consumption applications to control high current loads. Applications include audio amplification for computers, sound ports, sound cards and set-top boxes.

G1214A is housed in a small SOT-23-5 package.
