Biosensors bridge the divide between the living world and the digital world. Analog Devices’ biosensor solutions are powered by a range of integrated and discrete sensor and signal-conditioning technology solutions for portable, wearable, and bedside monitoring systems. Our integrated optical modules or sensor interfaces enable photoplethysmography (PPG) measurement for optical heart rate, heart rate variability, and pulse oximetry (SpO₂). Our high precision and low power analog front ends enable bioelectric measurement for electrocardiogram (ECG), EMG, EEG, and similar applications. ADI’s vital sign measurement portfolio ranges from optical sensors, bioelectric analog front ends, bioimpedance engines, low power motion sensors, and high precision temperature sensors.

Chemical analysis involves detection of light and the use of charged ion beams, redox reactions, and other technologies. Analysis methods including spectroscopy, spectrometry, and electrochemistry, which implement these technologies, are selected based on sample type and measurement characteristics. Accurate, high confidence detection, identification, and characterization depends on precise sensing capability and electronics. ADI’s best-in-class signal chain, sensor, and processor solutions ensure that your limit of detect (LOD) and accuracy are not restricted by your electronics design.

Gesture sensors using infrared-based dynamic optical sensors are able to sense a broad range of gestures at extended distances. The most recent generations of high performance gesture sensors from Analog Devices detect a wider proximity of movement and double the sensing range to 40 cm when compared to earlier generations, all in a quarter of the size and at 10× lower cost than time of flight (ToF) camera-based systems in automotive, industrial, and consumer applications.

Analog Devices MEMS gyroscopes and iSensor® MEMS gyroscope subsystems reliably sense and measure the angular rate of an object under complex and severe operating conditions. Our MEMS gyroscope portfolio includes analog and digital output, high vibration and shock immunity, and temperature sensitivity control to 25 ppm/°C. Measure an object’s rotation in °/sec over a wide dynamic range and bandwidth while leveraging our expertise to jumpstart your next design.

Analog Devices inertial measurement unit (IMU) sensors are based on multiaxis combinations of precision gyroscopes, accelerometers, magnetometers, and pressure sensors. Our technology reliably senses and processes multiple degrees of freedom, even in highly complex applications and under dynamic conditions. These plug and play solutions include full factory calibration, embedded compensation and sensor processing, and a simple programmable interface.

Magnetic field sensors are devices that detect and measure magnetic fields around permanent magnets, current conductors, and electrical devices. As the world becomes increasingly electrified, demand for improved positional and current sensing has grown in turn. ADI MagIC+™ breakthrough multiturn sensing technology operates with zero-power enabling more space-efficient solutions and ADI MagIC+™ magnetic field sensors create more accurate solutions. Analog Devices’ Magneto Resistive Sensing Technologies, signal conditioning capabilities, and deep domain expertise are enabling new, innovative, and high-performance sensing solutions for both position and current measurements across a broad range of applications and markets.

Analog Devices optical sensing devices achieve very high signal-to-noise ratios at the lowest power in the industry, making them ideal for battery-operated applications. Our portfolio covers the widest range of wavelengths available in an IC form factor, ranging from UV all the way up to 1600 nm in the near IR for your healthcare, automotive, and industrial applications.

Sensor hubs combine precision sensor interface electronics with firmware and algorithms to provide integrated solutions for wearable fitness, wearable medical monitoring, and other portable biosensor applications. High levels of integration ensure small solutions size, low component count, and low power consumption.

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.
