DESCRIPTION
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,
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, I
2
S, 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.
