The details on the new Teensy 4.1's specifications seem to be few and far between regarding its DAC and ADC features. I need to gather some high quality(0.000V to 2.200V), high frequency (~100Hz). I can see 3.X teensy's have the ability to set analog reference voltages, do the 4.X have this ability? I don't see it on the pinout. How good is the ADC on the 4.1? Thanks.
