3 Description

The TAD5112 is a Stereo 2VRMS DAC. The TAD5112

supports both differential and Single Ended input

and output. DAC Output can be configured for

either Line Out or Head Phone Load. TAD5112 can

drive upto TBD mW into a 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 filter modes, and

allows for sample rates up to 768 kHz. The TAD5112

supports Analog Input to Output Bypass option. 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.
