This audio adapter lets you easily add high quality 16 bit, 44.1 kHz sample rate (CD quality) audio to your projects with a Teensy 3.0 or 3.1. It supports stereo headphone and stereo line-level output, and also stereo line-level input or mono microphone input.

The audio chip connects to Teensy v3 using 7 signals. The I2C pins SDA and SCL are used to control the chip and adjust parameters. Audio data uses I2S signals, TX (to headphones and/or line out) and RX (from line in or mic), and 3 clocks, LRCLK (44.1 kHz), BCLK (1.41 MHz) and MCLK (11.29 MHz). All 3 clocks are created by Teensy3.1. The SGTL5000 chip operates in "slave mode", where all its clock pins are inputs.

Revision History:

  • 1. Pullup resistors are added for the SD card and optional SPI flash chip (the empty 8-pin location on the bottom side).
  • 2. The values of some capacitors are increased, to allow for better signals at sub-audible frequencies.
  • 3. A few locations are added to cut and join traces, to reconfigure the board to non-standard wiring.
