dc VOLTMETER


Posted on Feb 5, 2014

A wide-range voltmeter circuit. This inverting amplifier has a gain varying from -30 for the 10-mV full-scale range to -0. 003 for the 100-V full-scale range. Diodes D1 and D2 provide com-plete amplifier protection for input overvoltages as high as 500V on the 10-mV range, but if over-voltages of this magnitude are expected under continuous operati
