Audio Codec Board - PROTO, WM8731, 3.5mm Mic/Line Jacks, I2C/SPI US$19.00

Audio Codec Board - PROTO, WM8731, 3.5mm Mic/Line Jacks, I2C/SPI

  • Selectable ADC high-pass filter
  • ADC and DAC sampling frequency: 8 kHz to 96 kHz
  • SPI or I2C communication
  • Headphone and microphone connectors on board
  • The Audio Codec Board - PROTO is a development tool for the WM8731 Audio Codec, ideal for use in embedded applications which require audio playback. The on-board WM8731 provides stereo line and mono microphone level audio inputs. This module also uses stereo 24-bit multi-bit sigma-delta ADCs and DACs with oversampling digital interpolation and decimation filters. Stereo audio outputs are buffered for driving headphones from a programmable volume control. Line-level outputs are also provided along with anti-thump mute and power up/down circuitry. The device is controlled via 2-wire (I2C) or 3-wire (SPI) serial interface.

    Note: This board uses 3.3V power supply only. Be sure to use voltage translators on communication lines when connecting it to 5V systems.
