DESCRIPTION

The UTC PA7382A is a Class-AB audio power amplifier. As a

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

PA7382A is capable of delivering 3.0W of output power into 3Ω

BTL load with less than 10% distortion.

The UTC PA7382A 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 PA7382A features a low-power consumption

shutdown mode. The UTC PA7382A contains advanced pop &

click circuitry which eliminates noise which would otherwise occur

during turn-on and turn-off transitions. The UTC PA7382A is

unity-gain stable and can be configured by external gain-setting

resistors
