The temperature sensors that use the MAX1617MEE+T application field and working principle provide excellent accuracy for various applications, making them the ideal choice for thermometers, digital thermostats, and other temperature-sensitive devices. The MAX1617MEE+T is a low-power, three-terminal temperature-to-digital converter that employs an integrated thermistor to measure temperature for applications from -55°C to +125°C. The output is a 12-bit digital word. The MAX1617MEE+T can be operated in three different temperature ranges for optimizing both the thermistor, and A/D converter characteristics. The device is also customizable through pin-straps, allowing bias and gain compensation of thermistor to be optimized.

The MAX1617MEE+T employs a bridge excitation voltage that is generated on chip from a separate pin strap voltage that can range from 1.7V to 5.5V. This internal bias voltage is uniquely referenced to ground, thus greatly reducing device sensitivity to ground shift. Its built-in over temperature alarm provides a means to sense and respond to an out-of-range temperature, and is also programmable. The MAX1617MEE+T includes a Window Comparator Function for simplicity of operation.

The MAX1617MEE+T device offers a wide range of temperature sensing applications while providing optimal accuracy and power consumption. It provides temperature resolution of 0.0625°C and repeatability of 0.05°C, with no additional accuracy corrections required over temperature or time. Its unique floating ground architecture reduces the effects of ground voltage shifts on thermistor accuracy and offers unparalleled performance in harsh environment applications. The device also uses thermocouple compensation, allowing for lower cost thermocouples to be used with an acceptable level of resolution and repeatability.

The MAX1617MEE+T is used in a variety of applications such as cold-chain logistics, vehicle temperature management, medical and industrial process control, and home and building automation. It offers improved accuracy over traditional temperature measurement methods by using an integrated thermistor to measure temperature, eliminating the need for external temperature probe components and their associated calibration. Its flexibility makes it suitable for measurement in a wide variety of applications and environments.

The MAX1617MEE+T working principle is simple and reliable. It utilizes an external thermistor to sense temperature, which is then converted into a 12-bit digital number using a low-power Sigma Delta A/D converter. The thermistor resistance is converted into a voltage, which is sent to the A/D converter input. The A/D converter converts the analog voltage into a digital word that is sent to the output of the device. The output is a 12-bit digital word that can be used for various temperature-sensing applications.

The MAX1617MEE+T is designed to work with a wide range of thermistors and offers improved resolutions while reducing power consumption. It is simple to use and requires minimal external components.
