3 Description

The TAD5212 is a high performance Stereo 2VRMS

DAC. The TAD5212 supports both differential and

Single Ended input and output. DAC Output can be

configured for either Line Out or Head Phone Load.

TAD5212 can drive upto TBD mW into a Headphone

Load. The TAD5212 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 TAD5212 supports Analog Input to Output

Bypass option. Data from Analog-In and Digital-In can

be mixed inside the device as well. The TAD5212

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, make

TAD5212 an excellent choice for space-constrained

audio applications.
