G1214 Global Mixed-mode Technology Inc. Rail-to-Rail I/O, High-Slew-Rate OP Amp Features General Description G1214 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. G1214 can drive 66mA into resistor loads to within 10% power rail. AC performance is very excellent with 6.5MHz bandwidth, 6.5V/µs Slew Rate, 95dB open loop gain, 60 degree phase margin and low distortion. +3V to +5.5V Single-Supply Operation Input / Output Rail-to-Rail Low input current High output driving capacity Low Quiescent Current: 500µA @ 5V High Slew rate 6.5V/µs High Gain-Bandwidth Product 6.5MHz High Open Loop Gain 95dB High PSRR 70dB Supply current of G1214 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. Applications Headphone Driver Portable Equipment Battery-Powered Equipment Multimedia Audio ASIC Input or Output Amplifier Sensor Amplifier Low Power/Low Voltage Applications G1214 is housed in a 5-pin small SOT-23-5 and SC-70-5 package.
