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 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 an excellent choice for space-constrained audio applications.
