Temperature Sensors

Temperature Sensors

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.

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.

External Interface Temperature Sensors

Fan Speed Controllers

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.
