This Audio Adapter enables you to easily add high-quality, 16-bit, 44.1 kHz audio (CD quality) to your projects when used with a Teensy 3.2, 3.5, or 3.6. It supports both stereo headphone and stereo line-level output, along with stereo line-level input or mono microphone input, making it a versatile audio solution for various projects.
Key Features:
-
Audio Quality: Provides 16-bit, 44.1 kHz audio, offering CD-quality sound for your projects.
-
Stereo Output: Supports stereo headphone output and line-level output.
-
Stereo/Mono Input: Can handle stereo line-level input or a mono microphone input.
-
I2C Control: Utilizes the I2C pins (SDA and SCL) to control the chip and adjust settings.
-
I2S Audio Data: Uses I2S signals for audio data, including TX (to headphones/line-out) and RX (from line-in/mic).
-
Clock Signals: Requires three clocks, including LRCLK (44.1 kHz), BCLK (1.41 MHz), and MCLK (11.29 MHz), all generated by the Teensy 3.1.
-
SGTL5000 Chip: The audio chip operates in "peripheral mode", with all clock pins as inputs.
This audio adapter is perfect for adding high-quality audio functionality to your Teensy-based projects. Note: This product is the adapter only; the Teensy microcontroller is sold separately. If you're using a Teensy 4.0, you'll need the Audio Adapter Board for Teensy 4.0 instead.
