DESCRIPTION
The TLV320AIC34 is a low-power four-channel audio
codec with four-channel headphone amplifier, as well
as multiple inputs and outputs programmable in
single-ended
or
fully
differential
Extensive register-based power control is included,
enabling four-channel 48-kHz DAC playback as low
as 15 mW from a 3.3-V analog supply, making it ideal
for portable battery-powered audio and telephony
applications.
