ABSTRACT:
A transmitter includes a sensor adapted to sense a process variable and responsively provide a sensor analog output. An analog to digital converter provides a digitized output in response to the sensor analog output within a converter dynamic range. Signal range bracketing circuitry provides a bracketed range of the sensor analog output to the analog to digital converter for conversion. Outputs from the signal range bracketing circuitry and the analog to digital converter together provide a digital representation of the sensor analog output signal.
