Ok, sorry for this basic question, I am currently designing a sallen-key high pass filter using a TL072 opAmp, with the schematic shown below,
This circuit is connected to a piezo trasnducer whose signal I wnat to amplify. I was wondering, what do I connect to the Vcc+ and Vcc- pins of the op amp ? Should I connect a battery to each pin or is one of them (Vcc-) the ground ? I am aware this is a very basic question but I was just wondering. Also, say I put 18 volts into the amplifier, will this turn my amplified signal into 18 volts ? Thanks.
