Overview

The WS742133 is an integrated solution for Set-top box and high definition player, and designed to optimize the audio driver circuit performance while reducing the BOM cost by eliminating the peripheral discrete components for noise reduction. It features a 3Vrms stereo audio driver that allows for the removal of output AC-coupling capacitors. Featuring differential input mode, gain range of ±1 to ±10 can be achieved via external gain resistor setting. The WS742133 is able to offer 3Vrms output at 600Ω load with 5V supply. Meanwhile, it offers built-in shut-down control circuitry for optimal pop-free performance. Under under-voltage condition, it is able to detect it and mutes the output. WS742128 satisfies MSL3 level requirements.
