3 Description

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 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 TAC5242 an excellent choice for

space-constrained audio applications.
