The MAX11163ETB+T is an analog-to-digital converter that combines a high-performance 8-bit ADC with a temperature sensor in a tiny four-ball 3 mm x 3 mm WLP package providing an ideal solution for low-power portable and battery-powered applications. The MAX11163ETB+T supports precise and fast measurement of temperatures over the operating temperature range of -40°C to +85°C. The intent of this paper is to discuss the application field as well as the working principle of the MAX11163ETB+T.

Application Field: MAX11163ETB+T is applicable to measuring coefficient of temperature sensors like thermistors, RTD and other analog passive temperature sensing devices. It can also be used in monitoring the temperatures of internal components in electronic devices, such as microcontrollers, ASICs, etc. For example, the microcontroller can be used to monitor the environment temperature to protect its internal components. MAX11163ETB+T can also be used in medical devices, automotive systems, wireless communication, and industrial automation. Due to its high accuracy and low power consumption, MAX11163ETB+T is the preferred choice in low-power portable and battery-powered applications.

Working Principles: The MAX11163ETB+T works on a successive approximation ADC (SAR) method to convert analog signals into digital signals that microcontroller can process. The main function of an SAR ADC is to compare an analog input voltage with an internal reference voltage and provide a digitalcoded output. In the MAX11163ETB+T, the analog input is first compared with the internal reference voltage V_REF. If V_IN is lower than V_REF, then the MSB (most significant bit) of the result will be 0, otherwise it will be 1. This process is repeated until all 8 bits of the result have been calculated. The result is stored in the internal register, which can then be accessed through the serial interface. The MAX11163ETB+T also has an on-chip temperature sensor, which is used to measure the temperature at the chip. This, in turn, can be used to measure the temperature of the surrounding environment, or any other components that are close to the converter.

In summary, MAX11163ETB+T is an ideal analog-to-digital converter for low-power portable and battery-powered applications. Its high accuracy and low power consumption make it ideal for use in medical devices, automotive systems, wireless communication, and industrial automation. The MAX11163ETB+T uses the SAR ADC method to convert analog signals into digital signals that can be easily processed by microcontrollers. In addition, it also has an on-chip temperature sensor which can be used to measure the temperature of the environment or any other components near it.
