3 Description

The TAC5111 is a low-power mono audio codec with

2VRMS differential input, 105dB mono ADC and 2VRMS

differential output, 114dB mono or 1VRMS singleended

output, 107dB stereo DAC. The TAC5111

supports both differential and single-ended 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 TAC5111 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 TAC5111 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, makes TAC5111 an excellent

choice for space-constrained audio applications.
