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 times 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 effec-
tive 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 (See Figure 1),
eliminating the need for and cost of a precision reference.

FS (Full Scale) is defined as that of the operating temperature range, –50°C to +150°C. The listed max specification limit applies to the guaranteed temperature
range. For example, the AD22100K has a nonlinearity of (0.5%) × (200°C) = 1°C over the guaranteed temperature range of 0°C to +100°C.

WARNING!
ESD SENSITIVE DEVICE
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD22100 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
