Compact Low Power Precision Solutions

Analog Devices’ compact low power precision signal chains are designed and optimized for battery-powered, power-sensitive, or small footprint applications. Precision amplifiers, voltage references, analog-to-digital converters (ADCs), isolation, and microcontroller (MCU) components are combined for complete sensor-to-system solutions. These signal chains span key vectors including sensor type, sample rate, single-ended or differential sensor signals, and single-channel or multichannel systems. 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.
