3 Description

The TAD5242 is a 2VRMS 119dB Stereo DAC. DAC

Output can be configured for either Line Out or

Head Phone Load and supports both single ended

and differential output options. The device integrates

a phase-locked loop (PLL), a DC removal highpass

filter (HPF) and supports sample rates up to

192kHz. TAD5242 can drive upto 62.5 mW into

a Headphone Load. The TAD5242 supports timedivision

multiplexing (TDM), left-justified (LJ), or I2S

audio formats in controller and target mode, and

is pin controlled. These integrated high-performance

features, pin control along with a single supply

operation, make TAD5242 an excellent choice for

space-constrained audio applications.
