3 Description

The TAD5242 is a 2VRMS 120dB 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. TAD5242 can drive upto 62.5 mW

into a 16Ω headphone load. The TAD5242 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 TAD5242 an excellent choice

for space-constrained audio applications.
