Hello folks,
I am currently building a digital voltmeter (3 x IN-14, 1 x IN-19A)
using the 10 Bit ADC MAX1242 and the PIC16F627A as the controller. I
would like to measure voltages up to 300V.
Here is what I did:
- Vref was conencted to the 5V logic supply

- Vref was conencted to the 5V logic supply voltage, buffered with
2.2uF and 100nF.
