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.
