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.
Due to its ratiometric nature, the AD22100 offers a cost-
effective solution when interfacing to an analog-to-digital
converter. This is accomplished by using the ADC’s +5 V
power supply as a reference to both the ADC and the AD22100
eliminating the need for and cost of a precision reference (see
Figure 2).
