Getting 2 A/D and 2 D/A from Teensy 4

Hello,

How can I take 2 A/D and 2 D/A from Teensy 4?

Thank you

You just can’t. There is no builtin DAC on this board.

Can somehow connect external DACs? It would be great to use 12bit DACs.

Look at I2C or SPI DACs

Which is faster? Can I have 2 of them working in parallel?

I don't know which one is faster. Do a search for I2C DAC and the speed that you need; do the same for SPI DAC and the speed that you need.

You can hook them up in parallel. With I2C you need to specify an address for each (make sure that you can set the address on the module that you buy or that the IC has configurable addresses); for SPI, you simply activate the one that you want to control by pulling a line low (or high, not sure).
