I want mesure temperature with datashit scheme. Temperuture range is 0...150 (0C). Sensor is Pt100. I out is 1 mA. If I mesure 0 (0C) Uout is 100 mV, if I mesure 150 (0C) Uout is about 150 mV. Mesuring range is 50 mV. How I can offset 100 mV in ADC? I want gain 50 mV. I don't want gain 150 mV to get max resolution of ADC. Can I apply system offset calibration to get rid of displacement 100 mV?
