High-input-resistance-dc-voltmeter


Posted on Sep 29, 2012

This voltmeter exploits a number of tbe CA3160 BiMOS op amp`s useful characteristics. The available voltage ranges from 10 mV to 300 V. Powered by a single 8.4-V mercury battery, this circuit, with zero input, consumes approximately 500 p,A.
