#141105 - high voltage DC with ADC0804 |
Hi!!! I have to measure some kind of high voltage points in a circuit (+500v, -80V)
To do that, I thought to use 2 R's to make a resistive divisor an OPAMP for each point. Then, a MUX and then the ADC0804. I dont like the idea of not protecting the circuit, but I don't know what to use. http://img525.imageshack.us/img525/96...804eb0.jpg Can you help me? what do you think? thanks :) |

| make sure you use a high voltage resistor | 01/01/70 00:00 | |

| Be careful!!! 500V can be deadly!! | 01/01/70 00:00 | |
