Op amp dual power supply circuit
WebBut you should pay attention to these several premises: 1. CA3140 must be powered by dual power supplies. If it is a symmetrical positive and negative voltage, it is best (it is easier to analyze and implement), and the power supply voltage is better (the op amp is most suitable for larger Voltage, such as plus or minus 9V to plus or minus 15V); 2. WebAll sorts of battery powered guitar/bass effects pedals or active instrument preamps use a simple voltage divider as a dual power supply. Anything from 10K to 47K should work …
