Hi all,
I need to generate a variable DC voltage from -2vdc to +4vdc at less than 5mA. I would like to do this using the DAC output of a TeensyLC. The problem is I'm not sure how to properly do it and protect the Teensy from any possible damage from back feed on the signal wire. This signal is feeding the input of an OPAMP in an instrument. Do I need to feed the DAC output into an opamp to get a dual voltage output?
Thanks
Rob
