Dual 20 pin QFN package SGTL5000 on a single teensy 4.1

[microguy]

Hello,

Would like to know if there is a way to change i2c port used for SGTL500 : wire1, wire2 as only 20 pin package is available now.

If "yes" , can we use 2 SGTL5000 on the same Teensy?

One possibility is to use <this> 1-to-8 I2C Multiplexer from Adafruit (NOTE: I have not used this product personally, but I have seen mention of it in several other projects).

Using wire and wire1 you could use 2 SGTL5000

If you're using Rev D2 audio shields from PJRC, simplest solution would be to just get a Rev D audio shield for channels 3 & 4. All audio shields shipping today are Rev D with the larger chip.

Ok, I think I will go for a PCM5102 with no i2c...

Thanks you.
