The TAC5242 is a high performance Stereo Codec with 2VRMS differential Input, 118dB ADC and 2VRMS 119dB Stereo DAC. The TAC5242 supports both differential and Single Ended input and output. Device supports both Microphone and Line In input on ADC Channel. DAC Output can be configured for either Line Out or Head Phone Load. The device integrates a phase-locked loop (PLL), a DC removal high-pass filter (HPF) and supports sample rates up to 192kHz. TAC5242 can drive upto 62 mW into a Headphone Load. The TAC5242 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 TAC5242 an excellent choice for space-constrained audio applications.
