NJU7089
HIGH-POWER & LOW-VOLTAGE AUDIO POWER AMPLIFIER
■ GENERAL DESCRIPTION
The NJU7089 is an audio power amplifier designed for
telephone applications. No external coupling capacitors
are required because of the differential outputs. The
closed loop gain is adjusted by two external resistors,
and a SD pin permit power down with muting the input
signal.
The NJU7089 improves high output power compared
with other amplifier.
