8.1 Application Information

The TAC5112-Q1 is a stereo, low-power audio codec that supports sample rates of up to 768kHz. The device supports up to a total of 4 microphones for simultaneous recording which can be selected from up to 2 analog microphones or 4 digital pulse density modulation (PDM) microphones. The device also supports up to 4 channel simultaneous playback which can be configured as a 2-channel differential or psuedo-differential outputs or up to 4-channel single-ended outputs with options for headphone and line-out drive capabilities.

Communication to the TAC5112-Q1 for configuration of the control registers is supported using an I2C or SPI interface. The device supports a highly flexible, audio serial interface (TDM, I2S, and LJ) to transmit audio data seamlessly in the system across devices.
