Hello,

I have a DAC which output is 0 to 5Volts. I would like to amplify to +-15volts. Is there any common op.amp sch. or analog circuit/device for doing this?

Thanks a lot and best regards,

mimoto
 

The classical inverting circuit will work. Have the gain of six from your DAC and then another resistor to the summing junction to get the offset back down to zero.

You will have to use supply voltages of greater than 15V and a rail to rail output type amplifier.

The resistor to the summing junction should be connected to the Vref (2.5Volts), isn't it?.

I am thinking in using a non-inverting op.amp.
