Ok,
So, I have AC voltage from small current transformer for monitoring 230 V AC line 50 Hz
- 0,02V. I want to amplifie it to 6 V and use it with Pic microcontroler. Which op amp do you suggest?
Thanks
If you are only monitoring the presence of mains voltage, as distinct from measuring current in a mains-connected appliance, why not just use a 6V (or whatever) transformer and avoid the need for an opamp?
