Operational Amplifier Power Problem
I want to use the op amp as a voltage follower. The input voltage range is between 1V and 45V. I have found a few high-voltage power amplifiers on the Internet. 2142 seems to be fine. However, the datasheet says that it can be powered by a single power supply or dual power supply. VCC+ is +22V and VCC- is -22V. Then if I want a single power supply, add +44V to the positive power supply, can the negative power supply be grounded? If not, is there any other way?
