3 Description

The TAC5212-Q1 is a high performance Stereo

Codec with 2VRMS differential Input, 118dB Stereo

ADC and 2VRMS Stereo DAC. The TAC5212-Q1

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-Q1 can drive up to 62.5mW into

a Headphone Load. The TAC5212-Q1 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 768kHz. The TAC5212-Q1 supports timedivision

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, makes TAC5212-

Q1 an excellent choice for space-constrained audio

applications.
