Precision Low Power Solutions

Analog Devices’ precision low-power signal chains are designed and optimized for battery-powered, power-sensitive, or small footprint applications. We combine precision amplifiers, voltage references, analog-to-digital converters (ADCs), isolation, and microcontroller (MCU) components for complete sensor-to-system solutions. Our signal chains span across key vectors including sensor type, sample rate, single-ended or differential sensor input signals, and single-channel or multichannel capability. Applications include portable vital signs monitoring (VSM), wireless environmental monitoring (temperature, CO2 gas, CO gas, pH), condition-based monitoring (CbM), and industrial uses like intelligent flow meters and vibration sensing, including sensor biasing.

 

Value and Benefits

Precision low-power signal chains enable richer insights into our environment, the performance of distributed systems, and better understanding of human health by offering solutions that can be easily integrated and deployed into a variety of situations. These signal chains offer compact solutions with small footprints and battery-powered capability.
