Global Mixed-mode Technology Inc.
Quad Rail-to-Rail I/O, High-Slew-Rate OP Amp
Features
General Description
„
G1244 is a input/output rail-to-rail Operational Amplifier. It can be operated from +3V to +5.5V single supply or from ±1.5V to ±2.75 dual supply. G1244 can
drive 66mA into resistor loads to within 10% power rail
each amplifier. AC performance is very excellent with
2.5MHz bandwidth, 6V/µs Slew Rate, 95dB open loop
gain, 60 degree phase margin and low distortion.
