3 Description

The TAD5112-Q1 is a Stereo 2VRMS DAC. The

TAD5112-Q1 supports both differential and Single

Ended input and output. DAC Output can be

configured for either Line Out or Head Phone

Load. TAD5112-Q1 can drive upto TBD mW into

a 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 filter modes, and allows for sample

rates up to 768 kHz. The TAD5112-Q1 supports

Analog Input to Output Bypass option. Data from

Analog-In and Digital-In can be mixed inside the

device as well. The TAD5112-Q1 supports timedivision

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.
