Differential Amplifier – Op-Amp Circuits
This amplifies the difference between two inputs Vp and Vn the low impedance of this configuration is a drawback, but can be used in analog computing. Optimum VCC VDD can be +12/-12. AC signals...

Diode Thermometer
Measurement Of Temperature – When power transistors are used, they may tend to over heat. Likewise resistors may also overheat in the event of faults or short-circuits. The knowledge of their temperatures may be...
Mini RTD Pt100 Three Wire Transmitter
These are the circuits and boards of a Mini Temperature Transmitter for a Platinum hundred ohms temperature Sensor. Has a 4-20mA sink output. Current Loop can be used for multiple instruments.
Two Op-Amp Differential Amplifier
The Input Impedance of this module is very high and is symmetric. This circuit can be used for strain gauges and for four wire measurements. If inputs are in mV use OP07. The merit...
