AD22100: Voltage Output Temperature Sensor with Signal Conditioning
Product Description
The AD221001 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 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 (See Figure 2 of the datasheet), eliminating the need for and cost of a precision reference.
