Opto-Isolated-Input 4-Digit Voltmeter
The voltage that controls a V/F converter will be displayed when a frequency counter is used, which is directly proportional to the input voltage over a 1-second interval.
A Voltage-to-Frequency (V/F) converter is a critical component in various electronic applications, enabling...
High-input-resistance-voltmeter
A resistance of 1,000,000 MΩ takes advantage of the high input impedance of the CA3420 BiMOS op-amp. Only two 1.5-V AA-type penlite batteries are required for use. Full-scale deflection is ±500 nV, ±150 mV, and ±15 mV.
The circuit utilizes a...
Digital Voltmeter
The ICL7107 is a 3 1/2 digit LED A/D converter. It contains an internal voltage reference, high isolation analog switches, sequential control logic, and the display drivers. The auto-zero adjust ensures zero reading for 0 volts input.
The ICL7107 is a...
Peak (Pulse) Voltmeter
This is a Peak Voltmeter circuit. This circuit can be viewed as a pulse stretcher, which captures fast pulse signals to be measured by a slow response voltmeter.
The Peak Voltmeter circuit is designed to accurately measure the peak voltage of...
DIGITAL VOLTMETER CIRCUIT
A basic digital voltmeter circuit utilizing the Harris Semiconductor ICL7107 is presented. It operates within a 2-V range. Calibration involves applying a known voltage of 1.2 V to the input and adjusting resistor R3 to achieve an accurate reading on...
Suppressed zero meter
A zener diode placed in series with a voltmeter will prevent the meter from reading until the applied voltage exceeds the zener voltage. Thus, a 10-volt zener in series with a 5-volt meter will allow the condition of a 12...
