Hi All,
I am a complete noob here with analog circuits and I am trying to get the Teensy 3.2 to control a laser galvonometer.
I need an op amp circuit to convert the DAC single ended output from Teensy (0-3.3v) to a differential output (+5v to -5v). I have searched the web and found chips by Linear and Analog Devices that do this but they are MSOP8 packages (looking for DIP).
I am thinking that I would feed the DAC output to an Op Amp configure as a buffer amp for the positive side of the differential output (0 - +5v) and the also feed it into the (-) terminal of an differential Op Amp (0 - -5v) configured and the (+) input connected to 3.3v? On differential amp I would used the feedback resistors to adjust the gain.
I would welcome any suggestions on what op amp would be a good candidate for this application. I need between 20-30khz driver frequency.
Thanks in Advance!
