Abstract
A mapping circuit coupled to the integrator circuit of a delta-sigma converter to map the analog input range of the integrator to the analog out-put range of the sensor. The integrator circuit provides an integrator output to a controller to generate a digital output, which is in a digital output range representing the analog input range. A sensor input circuit includes a sensor having an analog sensor output range. The mapping circuit is coupled to the integrator circuit and is responsive to control signals from the controller to map the analog input range of the integrator to the analog output range of the sensor.
