EUA4992A - 2.25W Stereo Audio Power Amplifier

Download the EUA4992A datasheet PDF. This datasheet also covers the EUA4992 variant, as both devices belong to the same 2.25w stereo audio power amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

The EUA4992/4992A are dual bridge-connected audio power amplifiers, capable of delivering 1.25W of continuous average power to an 8Ω BTL with less than 1% distortion (THD+N) from a 5.0V power supply, and 540mW to an 8Ω BTL load from a 3.3V power supply.

EUA4992/4992A 2.25W Stereo Audio Power Amplifier DESCRIPTION The EUA4992/4992A are dual bridge-connected audio power amplifiers, capable of delivering 1.25W of continuous average power to an 8Ω BTL with less than 1% distortion (THD+N) from a 5.0V power supply, and 540mW to an 8Ω BTL load from a 3.3V power supply. The EUA4992/4992A provide high quality audio while requiring few external components and minimal power consumption. They feature a low-power shutdown mode, which is achieved by driving the SHUTDOWN pin with logic low. The EUA4992/4992A contain circuitry to prevent from ”pop and click” noise that would otherwise occur during turn-on and turn-off transitions.
