Features

Semi-Schematic PCB layout.
4 OpAmps on one PCB.
LM324 pinout.
Other pinouts than the LM324 possible.
Double rail powering.
Single rail powering.
“Free Style” Area.
Pads for pots / trim pots.
Backside Ground Plane: For less noise emissions and optimal signal strength.

The PCB is based on a IC with 4 opamps build in. Hence the X4.

The pinout follows the LM324 quad opamp: Datasheet – (LMx24, LMx24x, LMx24xx, LM2902, LM2902x, LM2902xx, LM2902xxx)

Create any circuit based on the pinout of the LM324 OpAmp with this board. It is hence not fixed to be used with one OpAmp circuit only, so you can add components according to your circuit.

The standard layout makes it easy to try out various different applications of the OpAmp.

About Opamps

Opamps are generally used for frequencies below 1 MHz. “Generally” means there are exceptions. If you want to use frequencies above 1 MHz, you would normally not use opamps, but transistors in your circuit. – See our selection if boards with transistors for those alternatives.

The PCB design is not specifically limited to 1 MHz, but the long traces between the IC and the additional components can potentially limit some use cases.
