描述 Description

The TAD5142 is a 2VRMS 106dB 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 high-pass filter (HPF) and supports sample rates up to 192kHz. TAD5142 can drive upto 62.5 mW into a Headphone Load. The TAD5142 supports time-division 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 TAD5142 an excellent choice for space-constrained audio applications.
