EUA4990 1.36 Watt Audio Power Amplifier DESCRIPTION The EUA4990 is an audio power amplifier designed for portable communication device applications such as mobile phone applications. The EUA4990 is capable of delivering 1.36W of continuous average power to an 8Ω BTL and with less than 1% distortion (THD+N) from a 5.0V power supply, and 460mW to a 8Ω BTL load from a 3V power supply. The EUA4990 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 EUA4990 contains circuitry to prevent from ”pop and click” noise that would otherwise occur during turn-on and turn-off transitions.
