3 Description

The TAC5211 is a high-performance mono audio

codec with 2VRMS differential input, 119dB mono

ADC and 2VRMS differential output, 120dB mono

or 1VRMS single-ended output, 111dB stereo DAC.

The TAC5211 supports both differential and singleended

inputs and outputs. The ADC supports both

line/microphone input signals with options for AC or

DC coupling configurations. The DAC outputs can

be configured for either line-output or headphone

loads. The DAC can drive up to 62.5mW into

a 16Ω headphone load. The TAC5211 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 and ultra-low latency filter modes,

and allows for sample rates up to 768kHz for

both ADC and DAC signal chains. The TAC5211

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

TAC5211 an excellent choice for space-constrained

audio applications.
