3 Description

The TAA5212 is a high performance Stereo ADC with

2VRMS differential Input, 118dB ADC . The TAA5212

supports both differential and Single Ended input.

Device supports both Microphone and Line In input

with AC and DC coupling options on ADC Channel.

The TAA5212 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 TAA5212 supports time-division multiplexing

(TDM), I2S, or left-justified (LJ) audio formats, and

can be controlled with I2C or SPI. These integrated

high-performance features, along with a single supply

operation, make TAA5212 an excellent choice for

space-constrained audio applications.
