EUA4992A
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 540m W to an 8Ω BTL load from a 3.3V power supply. The EUA4992/4992A provide high quality audio while requiring few external ponents 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. For maximum flexibility, the EUA4992/4992A provide an externally controlled gain (with resistors), as well as an externally controlled turn-on and turn-off times (with the bypass capacitor). The EUA4992/4992A are available in a 16-pin TQFN package.
