3 Description
The TAD5142 is a 2VRMS 110dB stereo audio DAC
that can be configured for either line output or
headphone load and supports both single-ended and
differential output options. The device integrates a
phase-locked loop (PLL) and supports sample rates
up to 192kHz. TAD5142 can drive upto 62.5 mW
into a 16Ω headphone load. The TAD5142 supports
time-division multiplexing (TDM), left-justified (LJ), or
I2S audio formats in controller and target modes, and
is pin or hardware controlled. These integrated highperformance
features, pin control along with a single
supply operation, make TAD5142 an excellent choice
for space-constrained audio applications.
