产品概述

The PCM3793/94 is a low-power stereo CODEC designed for portable digital audio applications. The device integrates stereo digital speaker amplifier, headphone amplifier, line amplifier, line input, boost amplifier, microphone bias, programmable gain control, analog mixing, sound effects, and automatic level control (ALC). It is available in a small-footprint, 5-mm × 5-mm QFN package. The PCM3793/94 accepts right-justified, left-justified, I2S, and DSP formats, providing easy interfacing to audio DSP, decoder, and encoder chips. Sampling rates up to 50 kHz are supported. The user-programmable functions are accessible through a two- or three-wire serial control port.
