This configuration is from a 1964 US documentation valid for any FET. The range of power voltages depends on the application.
The Texas Instruments INA826S Instrumentation Amplifier Evaluation Module is available from Mouser...
This circuit uses a FET and a BJT to give a x300 gain for the input signal. So a 50 mV signal at...
This circuit was found in an old 1980s valve documentation. The circuit can directly replace a...
