G1244D2U

Global Mixed-mode Technology Inc. G1244 Quad Rail-to-Rail I/O, High-Slew-Rate OP Amp Features +3V to +5.5V Single-Supply Operation Input / Output Rail-to-Rail Low input current High output driving capacity Low Quiescent Current: 2mA @ 5V High Slew rate 6V/µs High Gain-Bandwidth Product 2.5MHz High Open Loop Gain 95dB High PSRR 70dB General Description G1244 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. 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 applications 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.
