3 Description

The TAC5142 is a Stereo Codec with 2VRMS

differential Input, 100dB ADC and 2VRMS 106dB

Stereo DAC. The TAC5142 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 highpass

filter (HPF) and supports sample rates up

to 192kHz. TAC5142 can drive upto 62 mW into

a Headphone Load. The TAC5142 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 TAC5142 an excellent choice for

space-constrained audio applications.
