Details

This is an intermediate to advanced project and I do not recommend it as a first project if you are just getting started in synths or electronics. Only the circuit and some explanation are shown here. A lot of project building, troubleshooting and electronics experience is assumed. Additionally, electronic equipment ownership (scope, meters, etc.) is taken for granted. If you are interested in building this project please read the entire page before ordering PC boards to ensure that the information provided is thorough enough for you to complete the project successfully.

 

Introduction

The Swiss OpAmp Knife is for when you have an idea that requires some op amps and associated components and you want a quick PC board to accomodate the circuitry and you can't stand the thought of putting one of those phenolic single sided pieces of junk into your hand-crafted synth. I love this PC Board and putting together quick glue circuits has never been quicker or more convenient.

This product is definitely for you more seasoned hobbyists who already have ideas for op amp circuits and just need a quality place to put them without having to etch a board or use a low quality single sided phenolic kludge board.

 

 

Swiss OpAmp Knife PC Board Details

The Swiss OpAmp Knife accomodates a TL074CN quad op amp or any op amp whose pinout matches the TL074CN. It makes creating op amp based circuits quick and easy. Each of the four op amps has the same compliment of pads. The quad op amp package is bypassed with both .1uF caps right at the power pins and 10uF electrolytics where the power comes into the board. There are four input pad areas which can be routed to either the inverting or the non-inverting input via jumper. There are several floating pads. There are pads for the inverting and non-inverting inputs that align with the output of the op amp. This makes adding positive or negative feedback elements very convenient. There are pads that connect to ground, POS and NEG in case your circuit needs them. There are pads to accomodate biasing resistors. You can apply bias from any or all of the pads. Since you can use a two resistor voltage divider between POS and NEG to get any voltage in between the RG (resistor to ground) pads can be used for a voltage stabilization cap. In other circumstances you may prefer to bias using just RP and RG or just RN and RG. The inverting inputs are marked with the "-" symbols and the non-inverting inputs are marked with the "+" symbols.
