3 Description
The TAC5212 is a high performance Stereo Codec
with 2 VRMS differential Input, 118 dB Stereo ADC
and 2 VRMS Stereo DAC. The TAC5212 supports both
differential and Single-ended input and output. The
device supports both Microphone and Line In input on
the ADC Channel. DAC Output can be configured for
either Line Out or Head Phone Load. TAC5212 can
drive up to 62.5 mW into a Headphone Load. The
TAC5212 integrates programable channel gain, digital
volume control, a low-jitter phase-locked loop (PLL),
a programmable high-pass filter (HPF), programmable
EQ and biquad filters, low-latency filter modes, and
allows for sample rates up to 768 kHz. The TAC5212
supports time-division multiplexing (TDM), I2S, or leftjustified
(LJ) audio formats, and can be controlled
with I2C or SPI. These integrated high-performance
features, along with a single supply operation, makes
TAC5212 an excellent choice for space-constrained
audio applications.
