Data acquisition is the process by which a computer or other device measures and records data from the environment or from a living organism for later processing or analysis. One key component in data acquisition systems is the analog front end (AFE), which is responsible for receiving and conditioning analog signals from the environment and transmitting them to the registered converter or data insights processor. The AFE7222IRGCR is a low noise and low power AFE with AFG-Lite for high-accuracy thermal sensing applications. This article explores the application field and working principle of the AFE7222IRGCR.
Applications
The AFE7222IRGCR is targeted towards analog temperature sensing applications such as those found in consumer electronics and medical monitoring systems. This device is capable of measuring temperatures with high precision and accuracy while consuming relatively low power. It is powerful enough to be used as a reference design for various types of thermal sensing applications.
The AFE7222IRGCR also has integrated AFG-Lite generating functions, allowing it to generate and control PWM modulation in order to control the temperature at a certain level. This makes it an ideal device for use in medical and consumer-level thermal imaging systems. Additionally, the device is capable of measuring temperatures accurately up to 150°C, making it a suitable device for detecting events involving relatively hot temperatures.
Working Principle
The working principle of the AFE7222IRGCR lies in its ability to accurately and reliably read analog signals from a thermal sensor device. The device first receives the analog voltage from the sensor and then amplifies this signal via a multi-stage low-noise amplifier (LNA) before transferring it to the analog-to-digital converter (ADC). The amplified signal is then further filtered to improve dynamic range and resolution.
The ADC then converts the analog signal into digital data in order to be further transferred to a processor, such as a microcontroller, for further processing or analysis. Once the data is processed, the AFE7222IRGCR is capable of sending out an output voltage to an output device, such as an actuator or motor, in order to control the temperature of the measured environment.
Conclusion
The AFE7222IRGCR is an ideal analog front end for high-accuracy thermal sensing applications. It is capable of taking analog signals from sensors, amplifying and filtering them for better dynamic range and resolution, and then converting these signals into digital information for further processing or analysis. The device also has integrated AFG-Lite generating functions, allowing it to generate and control PWM modulation in order to control the temperature at a certain level. Finally, the AFE7222IRGCR can be used in various types of thermal sensing applications because of its ability to accurately measure temperatures up to 150°C.
