The AD22103KT is a monolithic temperature sensor with on-chipsignal conditioning. It can be operated over the temperaturerange 0°C to +100°C, making it ideal for use in numerous 3.3 Vapplications
The signal conditioning eliminates the need for any trimming,buffering or linearization circuitry, greatly simplifying the systemdesign and reducing the overall system cost.
The output voltage is proportional to the temperature times thesupply voltage (ratiometric). The output swings from 0.25 V at0°C to +3.05 V at +100°C using a single +3.3 V supply.
Due to its ratiometric nature, the AD22103KT offers a cost effectivesolution when interfacing to an analog-to-digital converter.This is accomplished by using the ADC’s power supply as a referenceto both the ADC and the AD22103,eliminating the need for and cost of a precision reference.
