The CS42L43 is an audio CODEC with integrated MIPI SoundWire interface (Version 1.2.1 compliant), I2C, SPI, and I2S/TDM interfaces designed for portable applications. It provides a high dynamic range, stereo DAC for headphone output, two integrated Class D amplifiers for loudspeakers, and two ADCs for wired headset microphone input or stereo line input. PDM inputs are provided for digital microphones. The MFD component registers and initialises the device and provides PM/system power management.
