#141107 - make sure you use a high voltage resistor Responding to: ???'s previous message |
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.
make sure you use a high voltage resistor, most resistors will 'cut theough' (especially in humidity) at higher voltages. I dont like the idea of not protecting the circuit, but I don't know what to use. if you can handle the capacitance a transzorb should do nicely. Erik |
