Abstract
A direct current transducer includes an open-loop Hall-effect sensor, a first ADC coupled to the open-loop Hall-effect sensor, a thermistor, a second ADC coupled to the thermistor, a manually controlled mode-selection device, a digital processor coupled to the first ADC and the second ADC, and digital memory coupled to the digital processor. The manually controlled mode-selection device is operative to develop an operating mode selection digital signal for a plurality of operating modes including a temperature-compensated direct current (DC) transducer mode and a calibration mode.
