DESCRIPTION

The UTC PA7382 is a Class-AB audio power amplifier. As a

power amplifier which is operating on a single 5V supply, the UTC

PA7382 is capable of delivering 3.0W of output power into 3Ω BTL

load with less than 10% distortion.

The UTC PA7382 does not require output coupling capacitors

or bootstrap capacitors, and therefore is ideally suited for mobile

phone and other low voltage applications where minimal power

consumption is a primary requirement.

The UTC PA7382 features a low-power consumption shutdown

mode. The UTC PA7382 contains advanced pop & click circuitry

which eliminates noise which would otherwise occur during turn-on

and turn-off transitions. The UTC PA7382 is unity-gain stable and

can be configured by external gain-setting resistors.
