Automotive low-power stereo audio DAC with 110dB dynamic range and headphone & line driver

The TAD5112-Q1 is an

automotive 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-Q1 supports both differential and

single-ended inputs and outputs. The DAC outputs can be configured for either

line-output or headphone loads. The TAD5112-Q1 can drive

up to 62.5mW into a 16Ω headphone load. The TAD5112-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 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-Q1 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-Q1 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 TAD5112-Q1 an excellent

choice for space-constrained audio applications.
