CS42L42 - Low-Power Audio Codec

Datasheet Summary

Description

The CS42L42 is a low-power audio codec with integrated MIPI SoundWire interface or I2C/I2S/TDM interfaces designed for portable applications.

It provides a high-dynamic range, stereo DAC for audio playback and a mono high-dynamic-range ADC for audio capture.

Features

  • Integrated fractional-N PLL.
  • Stereo headphone (HP) output with 114-dB dynamic range.
  • Increases system-clock flexibility for audio processing.
  • Class H HP amplifier with four-level automatic or manual supply adjust.
  • Reference clock sourced from either I2S/TDM bit clock or MIPI SoundWire clock.
  • Power output 2 x 35 mW into 30 .
  • Mono mic input with 114-dB dynamic range.
  • Low-noise headset bias with integrated bias resistor.
