Abstract
A microprocessor controller converts one or more sensor signals to a time multiplexed digital signal which is converted to an analog voltage signal by a digital-to-analog converter. A switching circuit, under the control of the microprocessor, selectively applies the analog signal to a plurality of current sources thereby setting the output current from each current source.
