General Description
G1214A is a input/output rail-to-rail Operational Ampli-
fier. It can be operated from +2.2V to +7V single sup-
ply 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 applica-
tions 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.
