General Description

G1214 is a input/output rail-to-rail Operational Ampli-

fier. It can be operated from +3V to +5.5V single sup-

ply or from

鹵

1.5V to

鹵

2.75 dual supply. G1214 can

drive 66mA into resistor loads to within 10% power rail.

AC performance is very excellent with 6.5MHz band-

width, 6.5V/碌s Slew Rate, 95dB open loop gain, 60

degree phase margin and low distortion.

Supply current of G1214 is only 500碌A(chǔ) 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.

G1214 is housed in a 5-pins small SOT23-5 package.

Applications

Headphone Driver
