产品概述

The PCM3793A/94A 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 PCM3793A/94A supports right-justified, left-justified, I2S, and DSP formats, providing easy interfacing to audio DSP and decoder/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.
