I've connected a DAC to a Raspberry Pi. The DAC gives a voltage between 0V and 3.3V.
I would like to convert this to an eurorack voltage between -5V and +5V.
As an editable schematic: (circuitjs)
In reality though, this doesn't work. I put it on a breadboard and measured with an oscilloscope and the output is between -2.5V and +2.5V. Note that I power the op amp with -5V and +5V. The op amp is an MCP6001.
What is wrong with this schematic? Am I right that I can't rely on circuitjs and masteringelectronicsdesign.com for this, or is my breadboard setup more likely to be incorrect?
*** UPDATE ***
I misunderstood op amps: they have a maximum difference between their Vss and Vcc (NOT neccessarily between 0V and Vcc) which can be fairly low like 6V
I misunderstood my function generator: 1.65Vpp means from -0.825 to +0.825 (NOT -1.65...+1.65V)
After replacing the op amp by a TL072, I indeed get a wave between -5V and +5V (almost, slightly less - suggestions for a better DIP op amp are welcome!)
I should use the -12/+12V from the eurorack power supply to feed the op amp
