General Description
G1244 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. G1244 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 G1244 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.
G1244 is available in 14-pins TSSOP package.
