It is also suited for use in low-power or battery-powered systems due to its low power consumption.

Working Principle

The AD8496CRMZ-R7 is a thermopile type temperature sensor amplifier. It utilizes the principles of thermoelectricity to measure temperature by converting heat energy into an electrical current. The sensor consists of two and-connected thermal sensing elements, one with a positive coefficient of thermal resistance, and one with a negative coefficient. By using this configuration, the output voltage is proportional to the temperature difference between the two elements.The device operates with a supply voltage between 1.8 and 3.6 V and an operating temperature range of -40°C to +125°C. To process the received signal, the device contains two identical differential amplifiers, which amplify the signal and then convert it into a single-ended output voltage. The output voltage is sent to an ADC, which then converts the voltage into a digital 8-bit value. This 8-bit value is then outputted through the serial bus.

Conclusion

The AD8496CRMZ-R7 is an integrated temperature sensor amplifier designed for use in a wide range of applications. It is an economical, accurate, and stable solution for many projects requiring temperature sensing. With its high impedance, low power consumption, and wide operating range, the AD8496CRMZ-R7 is a reliable and versatile choice for temperature measurement and control.
