GENERAL DESCRIPTION

The AD22100 is a monolithic temperature sensor with on-chip signal conditioning. It can be operated over the temperature range −50°C to +150°C, making it ideal for use in numerous HVAC, instrumentation, and automotive applications.

The signal 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 x the supply voltage (ratiometric). The output swings from 0.25 V at −50°C to +4.75 V at +150°C using a single +5.0 V supply.
