Thread: CV to teensy and vice versa

    CV to teensy and vice versa

    Hi,

    I'm trying to migrate a schematic I made around an arduino (nano) to teensy lc.
    This schematic converts a "control voltage" (-5...+5v) to ADC levels (0...5V) and the output of an MCP4725 to that control voltage.
    In case anyone is interested how I do that:

    to cv: https://www.falstad.com/circuit/circ...0+3+6+0+6+3%0A

    from cv: https://www.falstad.com/circuit/circ...6.4+0+2+9+3%0A

    My question now is: how do I do that with Teensy 3.3V levels? E.g. 0..3.3v to -5...+5v?

    I tried by trial & error and this is what I came up for 0...3 to +/-5 but it results in +/-2.5V instead: https://www.falstad.com/circuit/circ...625+1+2+6+3%0A

    Any suggestions?
