EUA4890 1 Watt Audio Power Amplifier

The EUA4890 is an audio power amplifier designed for portable communication device applications such as mobile phone applications. The EUA4890 is capable of delivering 1.0W of continuous average power to an 8Ω BTL and with less than 1% distortion (THD+N) from a 5.0V power supply, and 350mW to a 8Ω B.

EUA4890 Features

* a low-power shutdown mode, which is achieved by driving the SHUTDOWN pin with logic low. The EUA4890 contains circuitry to prevent from ”pop and click” noise that would otherwise occur during turn-on and turn-off transitions. For maximum flexibility, the EUA4890 provides an externally controlled gai
