Thank you for your reply!
I reviewed some application circuits for the IL300 and found the one you're talking about.
However I fail to understand how a 230 VAC signal can be reduced enough not to damage the input op amp.
You mean like this circuit?
I believe the left side would be the non-isolated part (AKA the VAC input) and the left would be my analog output.
Both sides have op amps which would be the reason for your suggestion to use a capacitor power source on the right side.

Hi,
I need to measure and log the power consumption of a AC device. So far I used an Arduino and an ACS712 current sensor and I assumed the voltage was always 230VAC as it's nominally stated.
However I noticed some variations on the voltage values which lead me to believe I need a more...
I'm using optocouplers to isolate a microcontroller from the power part of my circuit. Thing is I've burned all my MOC2011 (don't ask me how). Clearly I wasn't careful enough with the schematics. I don't have any left and I don't think I can get some for a few weeks.
The motor in question is a...
Hi there,
I was tearing apart some old cordless phone transmitter and I came across this curious component I've never seen before.
It has 5 pins (red) plus 2 through-hole holders (green). It seems is screw-regulated as it has a hole on top like some potentiometers I saw.
I'd really like to...
Damn, guess I'd have some sort of linear encoder (have lots-of from salvaged printers) or find a CD drive with a stepper.
(Hope to post in the future less trivial threads)
Thanks!
First of all hello there, this is my first thread.
So I started working on a mini cnc machine made from old CD drives. I plan to use the mechanisms to build a plotter like structure. When I tore them down I was expecting a stepper motor at the beginning of the lead screw, but what I got was a...
