Overview
The WS742128D 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. WS742128D features a 3Vrms stereo audio driver that designed to allow for the removal of output AC-coupling capacitors. Featuring single-ended input mode, gain range of ±1N to ±10/ can be achieved via external gain resistor setting. The WS742128D is able to offer 3Vrms output at 600Ω load with 5V supply. Meanwhile, the WS742128D offers built-in shut-down control circuitry for optimal pop-free performance. Under under-voltage condition, WS742128D is able to detect it and mutes the output. WS742128D satisfies MSL3 level requirements.
