Data Acquisition, mainly referring as the process of measuring real-world physical conditions, such as temperature, pressure, force, level or electrical signals and converting them into readable values for further processing, has been essential for a wide range of applications. For that, Analog to Digital Converters (ADC) are the key components to bridge the gap between analogue signals and digital data. Among those ADC solutions, MAX1402EAI+T Application Field and Working Principle is one of the early introduced solutions that has been developed for very low power and widespan voltage applications.

The MAX1402EAI+T is a low power, low voltage sigma-delta converter that can be used in a wide range of applications from battery-powered measurement systems to medical applications. As its name implies, it combines the benefits of an ADC together with its integrated temperature sensor, which make it an ideal solution for temperature sensing applications with high accuracy. It also boasts an impressive power efficiency rating, with a minimum 15.2µA typical shut-down current.

The principle behind the MAX1402EAI+T is based on the industry standard Sigma Delta technology. This technology is based on a sigma-delta non-overlap modulation technique, in which a signal is generated using a modulator known as a sigma-delta modulator. In practice, a signal is composed of a finite-length sequence of voltage levels, known as the signal envelope. This signal envelope can be thought of as a digital signal, although in reality it consists of a finite-length set of analog voltages.

The MAX1402EAI+T is capable of converting the incoming analog signal into digital data with an excellent resolution, accuracy and low power consumption. The device is designed to operate on an external voltage references ranging from 1V to 3V while consuming only 4µA (at 1.25V). Furthermore, due to its wide operating temperature range (from -40°C to +125°C), the MAX1402EAI+T is suitable for temperature measurement applications.

In addition, the MAX1402EAI+T allows for a three wire interface for a SPI/I2C compatible serial loader and self-calibration enable in its working mode, making it ideal for battery powered applications. Furthermore, the device has the capacity to read temperatures of up to +150°C with a resolution of 0.25°C. With such features and advantages, it makes the MAX1402EAI+T a great choice for embedded temperature sensing applications.

The MAX1402EAI+T is an excellent solution for systems that need precision temperature sensing. It is an ideal choice for portable and embedded applications that require both low-power and accurate temperature readings. It can be used in any application that requires temperature to be measured, controlled and/or monitored over a wide range. Overall, the MAX1402EAI+T is an important component of data acquisition that has myriad potential applications.
