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

the UTC PA4990 is capable of delivering 1.2W of output power into

8Ω loads with less than 1% distortion.

The UTC PA4990 is optimally suited for applications: Mobile

phones (cellular/cordless), notebook computers PDAs and Portable

audio devices.

The shutdown mode can reduce the supply current to less than

10nA. It also includes thermal shutdown protection internally. By

external gain setting resistors the gain can be configured.
