AD22100A

General description

The AD22100 is a monolithic temperature sensor with on-chip signal conditioning. With a temperature range of -50°C to +150°C, it is suitable for use in many 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 costeffective 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.

Process :
1. Read AD conversion value.
2. Convert AD conversion value to Temperature.
Voltage value = (AD conversion value × VDD) / ( 2AD bit )
Temperature = ((voltage value – voltage offset value) / gain) + Temperature offset value (Min, Max Limit)
3. Store Temperature to rlt.

eCMD_START_READ

Feature :
Command that starts AD conversion, waits for AD conversion to finish, reads out the AD conversion value, converts the AD conversion value to a characteristic Temperature, and stores the Temperature in rlt.

Process :
1. AD conversion start.
2. Wait until AD conversion is completed.
3. Read AD conversion value.
4. Convert AD conversion value to Temperature.
Voltage value = (AD conversion value × VDD) / ( 2AD bit )
Temperature = ((voltage value – voltage offset value) / gain) + Temperature offset value (Min, Max Limit)
5. Store Temperature to rlt.
