DESCRIPTION
SLAS479B – AUGUST 2005 – REVISED AUGUST 2006
LOW POWER STEREO AUDIO CODEC FOR PORTABLE AUDIO/TELEPHONY
Stereo Audio DAC
The TLV320AIC32 is a low-power stereo-audio
codec with a stereo headphone amplifier, as well as
– 100 dB A Signal-to-Noise Ratio
multiple
inputs
and
outputs,
programmable
in
– 16/20/24/32-Bit Data
single-ended
or
fully-differential
configurations.
– Supports Rates From 8 kHz to 96 kHz
Extensive register-based power control is included,
– 3D/Bass/Treble/EQ/De-Emphasis Effects
enabling stereo 48-kHz DAC playback as low as 14
mW from a 3.3-V analog supply, making it ideal for

Power Supplies:
gain amplifiers providing up to +59.5 dB analog gain
– Analog: 2.7 V – 3.6 V
for low-level microphone inputs.
– Digital Core: 1.525 V – 1.95 V
The serial control bus supports the I2C protocol,
– Digital I/O: 1.1 V – 3.6 V
while the serial-audio data bus is programmable for
I2S, left/right justified, DSP, or TDM modes. A highly
