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 circuit can oscillate at frequencies up to a few tens of megahertz depending on the crystal. The...
This circuit was obtained from Maxim documentation. The circuit has 4.5 and 5.5V thresholds for...
This circuit can be used with motors or resistive loads, such as heaters and incandescent lamps....
