GENERAL 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 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 effec-
tive solution when interfacing to an analog-to-digital converter.
This is accomplished by using the ADC’s power supply as a ref-
erence to both the ADC and the AD22103 (See Figure 1),
eliminating the need for and cost of a precision reference.
