I intend to implement four adjustable voltage signals to control curent sources of different types. Current sources are tested and work OK.
Control is basically up/down with a fixed minimum value at turn on (eventually I could retain the last in use at turn off).
After much reading I focused on two quad options by Microchip: DAC MCP4728 or digipot MCP4361. Datasheets attached.
Besides the complexity of controlling software with a small micro (not a problem for me), what is your opinion about which one to choose?
Comments, suggestions appreciated. No previous experience on this myself.
