Features
+3V to +5.5V Single-Supply Operation Input / Output Rail-to-Rail Low Input Current High Output Driving Capacity Low Quiescent Current: 1mA @ 5V High Slew Rate 6V/µs High Gain-Bandwidth Product 2.5MHz High Open Loop Gain 95dB High PSRR 70dB
Applications
Headphone Driver Portable Equipment Battery-Powered Equipment Multimedia Audio ASIC Input or Output Amplifier Sensor Amplifier Low Power/Low Voltage Applications General Description G1224 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. G1224 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 G1224 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. G1224 is available in 8pins SOP-8, MSOP-8, TSSOP-8 and SOT-23-8 package.
