Temperature Sensor and Control Devices

Temperature Sensor and Control Devices

Analog Devices temperature sensor devices sense and measure temperature with precise accuracy and reliability. Our temperature sensor products support an analog output and a digital output format to suit a large array of end applications in all traditional markets such as industrial, communications, and automotive, as well as emerging areas such as digital healthcare. Analog Devices temperature sensors achieve up to ±0.1°C measurement accuracy over a wide temperature range, are NIST traceable, and are plug-in ready, often requiring no additional signal conditioning or calibration. Additionally, ADI digital temperature sensors may integrate other functions such as DACs, ADCs, references, and limit alarm registers. A range of interfaces are available, including I²C, SPI, and PWM (for digital products) and current and voltage (for analog products). Analog devices temperature sensor devices come in a large variety of package options including ceramic and metal packages for increased robustness, and plastic and WLCSP for applications where sensor size is critically important. All temperature sensors manufactured by Analog Devices are tested and calibrated in production, eliminating the need for post-assembly system calibration.

Analog Temperature Sensors

Analog Devices analog temperature sensors provide current or voltage output proportional to the absolute temperature with accuracies of up to ±1°C. Our diverse range of analog output temperatures sensors can be used in a broad range of applications with no need for external calibration, and with minimal signal conditioning/conversion circuitry. To better suit your varied design needs, our portfolio of temperature sensors are available in multiple package options.

Clinical-Grade Temperature Sensors

Life sciences and biotechnology instrumentation require accurate and high resolution temperature sensing. Analog Devices’ temperature sensor devices sense and measure temperature with precise accuracy and reliability. ADI’s temperature sensors achieve up to ±0.1°C measurement accuracy over a wide temperature range, are NIST traceable, and are plug-in ready, often requiring no additional signal conditioning or calibration. Additionally, ADI digital temperature sensors may integrate other functions such as DACs, ADCs, references, and limit alarm registers.

Digital Temperature Sensors

Analog Devices offers a broad selection of digital temperature sensors with I2C, SPI, and mark space interfaces. For more intricate system design applications, some of these sensors have integrated D/A converters, A/D converters, references, and limit alarm register. All of these sensors possess a broad range of uses, including scientific, medical, and aerospace applications, in test and measurement equipment, and in industrial automation.

RTD Interface

Resistance temperature detectors (RTDs) are sensors whose resistance changes with temperature. RTDs require precision signal conditioning circuitry for converting sensor output to an accurate temperature reading. Analog Devices’ family of precision RTD signal conditioners include high performance amplifiers, voltage references, and excitation circuitry. Because RTDs can be located some distance from the signal conditioning circuitry and the cables can be exposed to potentially damaging voltage levels, many of our RTD interface products offer internal voltage protection and fault detection and protection. ADI RTD products are optimized for a wide range of RTD materials and resistances, including PT100 to PT1000, and can be used for other resistive sensors such as thermistors.

Temperature Data Loggers

Analog Devices’ Thermochron^® family of iButton^® devices (DS1921/DS1922/DS1925) is made up of temperature data loggers that track the temperature of specific assets or locations. Now you can easily log the thermal exposure of an asset during shipment to see if it stays within specified temperature ranges. Thermochron data loggers make it simple and inexpensive to monitor anything that is temperature sensitive, including pharmaceuticals (vaccines, drugs, reagents), fresh or frozen foods (fruits, vegetables, dairy/dessert products), biological items (animals, blood products, soil), or heating/refrigeration/freezer systems. The Thermochron data logger can also be used for warranty-tracking purposes on equipment that must be kept within a certain temperature range, or to log the results of a process that must be monitored for compliance to a temperature profile. Like all iButton devices, the stainless-steel casing of a Thermochron data logger makes it rugged, reusable, and portable. It is so small that it fits anywhere and can deliver years of reliable, highly accurate temperature readings.

Temperature Switches

Analog Devices temperature switches monitor temperature and activate digital output when measurements exceed the trip point setting. To meet differing design needs, we provide pin selectable, factory set, and user programmable trip point setting options. With support for a wide range of operating temperatures and without the need for external calibration, our portfolio of temperature switches also enables swifter design and production with faster time to market. Analog Devices temperature switches come in small, low count plastic packages, operate at low supply voltages down to 2.7 V, and are power optimized—consuming typically less than 100 μA of current.

Thermocouple Interface

Analog Devices offers specialized precision thermocouple interface amplifiers that provide a simple and effective solution for measuring thermocouple temperatures. With features such as integrated cold junction compensation and a high gain precision instrumentation amplifier, these thermocouple amplifiers provide a complete signal conditioning system in one IC package. ADI’s thermocouple amplifiers are suitable for use in diverse environments to measure a wide range of temperatures. These products will save you in cost, space, and unnecessary circuit design across a broad range of applications and industries.
