Description:

Mono class d and stereo audio subsystem.

LM4947, Mono Class D and Stereo Audio Subsystem

The LM4947 is an audio subsystem capable of efficiently delivering 500mW (Class D operation) of continuous average power into a mono 8Ω bridged-tied load (BTL) with 1% THD+N, 37mW (Class AB operation) power channel of continuous average power into stereo 32Ω single-ended (SE) loads with 1% THD+N, or

LM4947 Features

* a 32-step digital volume control and eight distinct output modes. The digital volume control, 3D enhancement, and output modes are programmed through a two-wire I2C compatible interface that allows flexibility in routing and mixing audio channels. The RF suppression circuitry in the LM4947 makes it
