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 0.25V 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.
