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 0.1 A typical.
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.
