■ GENERAL DESCRIPTION
The NJM2770 is high-power and low-voltage audio power amplifier with standby function. No external coupling capacitors required because of the differential output type. Two external resistors adjust the closed loop gain. The output power is 250mW typical at 3V-supply 8ohm-load, and 400mW typical at 4.5v-supply 16ohm-load. The standby current is only 0.1µA typical.
The package of NJM2770 is VSP8, and suitable for PCS, codeless telephone, speaker amplifier for hands free system, and especially cellular phone because of low operating current, low standby current, and high power output.
