This circuit makes use of a 741 single source operational amplifier to measure resistors on a linear scale. The circuit may use as an indicator a common multimeter on a low current range.
This circuits shows how to use in operational amplifier as a basic voltmeter. Power supply must be...
The coils determine the frequency of this oscillator that we found in the January 1996 issue of...
This circuit was found in a National Semiconductor Handbook from the 1990s. The integrated circuit...
