Hardware Modules > aMG SIGCON-A

aMG SIGCON-A is a simple general purpose op-amp breakout board. It has been designed to be highly flexible. You can create any op-amp application circuits such as inverting, non-inverting amplifier, voltage follower, LP filter, etc., by soldering some R, C or wire jumper at the specific positions using reference circuit diagrams.
