G1211
Global Mixed-mode Technology Inc.
Rail-to-Rail I/O, High-Slew-Rate OP Amp
Features
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.
