Quad Single-Supply Operational Amplifier

The NJM2902 consists of four independent high-gain operational amplifiers that are designed for single-supply operation. Operation from split power supplies is also possible and the low power supply drain is independent of the magnitude of the power supply voltage. Used with a dual supply the circuit will operate over a wide range of supply voltages. However, a large amount of crossover distortion may occur with loads to ground. An external current-sinking resistor to-V_s will reduce crossover distortion. There is no crossover distortion problem in single-supply operation if the load is direct-coupled to ground.
