3 Description

The TAA5242 is a high performance Stereo ADC with

2VRMS differential Input, 118dB ADC . The TAA5242

supports both differential and Single Ended input.

Device supports both Microphone and Line In input

with AC and DC coupling options on ADC Channel.

The TAA5242 integrates digital volume control, a low-jitter

phase-locked loop (PLL), a configurable highpass

filter (HPF), and allows for sample rates up

to 768 kHz. The TAA5242 supports time-division

multiplexing (TDM), I2S, or left-justified (LJ) audio

formats, and can be controlled with Pin control. These

integrated high-performance features, along with a

single supply operation, make TAA5242 an excellent

choice for space-constrained audio applications.
