ABSTRACT:
A temperature compensating circuit for taking into account operating temperature changes of a Hall effect transducer to compensate for Hall output DC offset changes using a resistance circuit including a thermistor for offset feedback control of an operational amplifier in accordance with varying temperature. The circuit also includes a load response input portion to power the Hall effect transducer to compensate for Hall gain change versus temperature.
