General Description
G1224 is a input/output rail-to-rail Operational Ampli-
fier. It can be operated from +3V to +5.5V single sup-
ply or from ±1.5V to ±2.75 dual supply. G1224 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.
Supply current of G1224 is only 500µA per Amplifier. It
is very suitable for low current consumption applica-
tions to control high current loads. Applications include
audio amplification for computers, sound ports, sound
cards and set-top boxes.
G1224 is available in 8pins SOP-8, MSOP-8.
