Hello, my name is Miguel and I am from Portugal. Sorry in advance for my english.
I was looking for the best way to get symetrical voltages from one single voltage to bias op amps. Getting -/+5V with a 10 or 12V supply for example.
First I thought of a voltage divider, with just two resistors. But than I realized that it could became instable.
Then it came to my mind that I could use linear regulators like 78xx and 79xx.
Can you help me in finding the best way?
Thank you in advance for your help.
Miguel
