hi, Im making a over network-contorled drone,
and I hacked a drone controller, made other things but
my system is making voltage different value when i use other power supply (or even when I use same battery but less charged), with same pwm.
so, i'm trying to use DAC.
need to make 1.400~1.900V +-0.01V precission of 4 output channel
can this be the sollution?
=========================================================================
DAC : https://www.analog.com/media/en/technical-documentation/data-sheets/DAC8420.pdf
with 2.5 voltage reffernce chip, single 5V supply system, MCU: arduino micro.
