7.1 Application Information

The TAA5242 is a pin or hardware controlled stereo, high-performance audio ADC that supports sample rates of up to 192 kHz. The device can be configured by controlling the Mode pins MD0 to MD6 and can support 1.8V or 3.3V AVDD analog power supply along with flexible digital audio interfaces of I2S/TDM/LJ. The device has differential and single-ended input capabilities and can support both line-in and microphone inputs for stereo recording with high dynamic range.
