G1213
Low power, Single, SOT23-5, Rail-to-rail OP Amp
Features
Single-Supply Operation: 4V to 6V High Output Current: 100mA Low Supply Current: 500 A Wide Bandwidth: 3 MHz Slew Rate: 4 V/s No Phase Reversal Unity Gain Stable Small, 5-Pin SOT23 Package available
General Description
The G1213 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/s 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 G1213 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 850A per amplifier at 5 volts, allowing low current applications to control high current loads. Applications include audio amplification for computers, sound ports, sound cards and set-top boxes. The G1213 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.
Applications
