This circuit uses an unusual sensor nowadays, but the configuration can be adapted to more modern types, as well as the operational amplifier. The circuit is from an 80's documentation.
This is a bridge for the measurement of low value resistances and high values too. The circuit...
This inverter bistable buffer circuit was obtained in a Hands On of the 90's. Next to the circuit we...
Other series amplifiers such as the MC3301, MC3401 and LM2900 can be used on this circuit. We...
