TLV320AIC32
SLAS479A – AUGUST 2005 – REVISED SEPTEMBER 2005
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 multiple
– 100 dB A Signal-to-Noise Ratio
inputs and outputs, programmable in single-ended or
