G1224 can drive 66ma into resistor loads to within 10% power rail each amplifier. ac performance is very excellent with 2.5mhz bandwidth, 6v/s slew rate, 95db open loop gain, 60 degree phase margin and low distortion. supply current of G1224 is only 500a 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. ordering information order number marking temp. range package (pb free) G1224p1u G1224 0c to 85c sop-8 G1224p8u G1224 0c to 85c msop-8 note: p1: sop-8 p8: msop-8 u: tape & reel pin configuration typical application circuit outa sop-8/msop-8 1 2 3 4 5 6 7 8 G1224 v dd outb inb- inb+ ina- ina+ v ss - + - + G1224 4 3 2 1 rl 2k outa ina+ + - + vdd 8 outa sop-8/msop-8 1 2 3 4 5 6 7 8 G1224 v dd outb inb- inb+ ina- ina+ v ss - + - + G1224 4 3 2 1 rl 2k outa ina+ + - + vdd 8 G1224 4 3 2 1 rl 2k outa ina+ + - + vdd 8
