#92301 - overcomming opto difference Responding to: ???'s previous message |
If you use opto's with a transistor base pin, you can make them constant current generators feeding an op-amp summing point ( the op-amp becomes a current to voltage converter).
Then the differences between the optoisos will virtually disappear. Erik |
