For the i2s Audio Breakout Board (https://www.sparkfun.com/products/14809) what is the current when being put into shutdown mode with the shutdown pin?
Thanks for reaching out to us on this.
The datasheet lists “Shutdown Current ISHDN SD_MODE = 0V, TA = +25°C 0.6-2 µA” on page 4 here

The rest of the datasheet has everything else we know about it 
Hope this helps, and happy sparking!
