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.
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.
