Rail-to-Rail I/O, High-Slew-Rate OP Amp
Features
General Description
„
G1214 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. G1214 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.

+3V to +5.5V Single-Supply Operation
Input / Output Rail-to-Rail
Low input current
High output driving capacity
Low Quiescent Current: 500µA @ 5V
High Slew rate 6.5V/µs
High Gain-Bandwidth Product 6.5MHz
High Open Loop Gain 95dB
High PSRR 70dB
Supply current of G1214 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.
