3 Description

The TAD5112 is a low-power audio DAC with

2VRMS differential output, 110dB dynamic range

stereo channels or 1VRMS single-ended output,

107dB dynamic range quad channels. The TAD5112

supports both differential and single-ended inputs

and outputs. 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 TAD5112 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 the DAC and PDM

microphone signal-chains. The TAD5112 supports

analog input to output bypass option and also

recording up to four-channel digital microphones with

the PDM interface. Data from Analog-In and Digital-In

can be mixed inside the device as well. The TAD5112

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

TAD5112 an excellent choice for space-constrained

audio applications.
