This circuit was found in a Mallory documentation from 1968. The integrated circuit is of the time, unusual in our day. Input sensitivity is 20 mV for 2 W output.
This circuit, suggested by National Semiconductor, provides an output voltage proportional to the...
The integrated circuit used in this 1982 project is not very common today. It can be adapted to...
The sensors in this circuit are NTCs and PTCs that work in a differential way by directly...
