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 high-performance features, pin control along with a single supply operation, make TAD5142 an excellent choice for space-constrained audio applications.
