G1211 Global Mixed-mode Technology Inc. Rail-to-Rail I/O, 100mA Output Op Amp Features General Description Single-Supply Operation: 4V to 6V High Output Current: ±100mA Low Supply Current: 500 µA Wide Bandwidth: 3 MHz Slew Rate: 4 V/µs No Phase Reversal Unity Gain Stable Ultra-Small, 5-Pin SC70 Package The G1211 is a rail-to-rail input and output single-supply amplifiers featuring 100mA output drive current. This high output current makes these amplifiers excellent for driving either resistive or capacitive loads. AC performance is very good with 3.0MHz bandwidth; 4.0V/µs slew rate and low distortion. All are guaranteed to operate from a +4 to +6 volt single supply. The very low input bias currents enable the G1211 to be used for integrators and diode amplification and other applications requiring low input bias current. The 100mA high output current and supply current is only 850µA per amplifier at 5 volts, allowing low current applications to control high current loads. Applications Battery-Powered Instruments Portable Equipment Audio Signal Conditioning High-Side/Low-Side Current Sensors Multimedia Audio ASIC Input or Output Amplifier Headphone Driver Applications include audio amplification for computers, sound ports, sound cards and set-top boxes. The G1211 is very stable and capable of driving heavy capacitive loads. The ability to swing rail-to-rail at the inputs and outputs enables designers to buffer CMOS ADC/DACs, ASICs or other wide output swing devices in single-supply systems.
