EUA4890A

The EUA4890A is an audio power amplifier designed for portable communication device applications such as mobile phone applications. The EUA4890A is capable of delivering 1.0W of continuous average power to an 8 BTL and with less than 1% distortion (THD+N) from a 5.0V power supply, and 350mW to a 8 BTL load from a 3V power supply.

The EUA4890A provides high quality audio while requiring few external components and minimal power consumption. It features a low-power shutdown mode, which is achieved by driving the SHUTDOWN pin with logic low.

The EUA4890A contains circuitry to prevent from "pop and click" noise that would otherwise occur during turn-on and turn-off transitions.

For maximum flexibility, the EUA4890A provides an externally controlled gain (with resistors), as well as an externally controlled turn-on and turn-off times (with the bypass capacitor).

The EUA4890A is available in a 1.5mm*1.5mm WCSP package.
