What is AMS39K?
The AMS39K is a high-precision digital temperature sensor designed to monitor and output temperature readings in a wide array of environments. It integrates a Negative Temperature Coefficient (NTC) thermistor that changes its resistance predictably with temperature variations.
This change is processed by the device’s internal circuitry, which then outputs a digital temperature reading. With an extended operating temperature range from -55°C to +150°C, AMS39K provides industry-leading accuracy of ±1°C, making it ideal for demanding environments.
The Functionality of AMS39K
At the core of the AMS39K is its thermistor-based design. Thermistors are temperature-sensitive resistors that change resistance based on the surrounding temperature.
AMS39K uses an NTC thermistor, which means that as the temperature rises, the resistance of the thermistor decreases. This change is precisely measured by an onboard analog-to-digital converter (ADC), which converts the thermistor’s resistance value into a corresponding digital temperature output.
This process involves several stages:
-
Sensing Element:
The NTC thermistor embedded within the AMS39K senses temperature variations.
-
Resistance Measurement:
The resistance of the thermistor is measured by the integrated ADC, which is designed to accurately convert these resistance values into a digital format.
-
Voltage Conversion:
The analog resistance readings are converted into a digital voltage value.
-
Temperature Calculation:
The microcontroller or external system receiving the output uses the sensor’s calibration data to convert the voltage value into a temperature reading.
-
Output:
The temperature data is output via I2C or SPI interfaces, allowing easy integration into microcontrollers or processors for system monitoring.
The use of digital output via I2C or SPI simplifies the interface with external systems and ensures that the data is accurate and easy to read, making it ideal for applications requiring real-time feedback.
