Hello all,
I am powering an MCP4725 DAC using the Teensy 4.1. I would like to boost the 3.3v output of the DAC to 5v, to produce control voltage for use in a modular synth environment.
My first question is simple: Can I power the DAC straight from a 5v rail, or should I use something like a logic level shifter to get a 5v output? If neither of those are correct I assume I need to build an amplifier circuit following the DAC.
Secondly, while I'm still prototyping I'd prefer to power the Teensy using USB. If level shifting is necessary to amplify the DAC output, I have an Arduino to supply 5v from the pin. And if level shifting is necessary, is it safe to use the Teensy's 3.3v pin for the LV of the level shifter, and the 5v pin from the Arduino as the HV?
Going off of total guess work here, so if this is way off the mark, I'm open to any suggestions. Thanks!
