Description

The AD22103 is a monolithic temperature sensor with on-chip signal conditioning. It can be operated over the temperature range 0°C to +100°C, making it ideal for use in numerous 3.3 V applications.

The signal of AD22103 conditioning eliminates the need for any trimming, buffering or linearization circuitry, greatly simplifying the system design and reducing the overall system cost.

The output voltage is proportional to the temperature times the supply voltage (ratiometric). The output swings from 0.25 V at 0°C to +3.05 V at +100°C using a single +3.3 V supply. Due to its ratiometric nature, the AD22103 offers a cost effective solution when interfacing to an analog-to-digital converter.

This is accomplished by using the ADC's power supply as a reference to both the ADC and the AD22103 (See Figure 1), eliminating the need for and cost of a precision reference.
