PRECISION LOW POWER
PRECISION LOW POWER
Analog Devices’ precision low power signal chains are designed and optimized for small-size battery-powered or power sensitive applications. ADI’s solutions combine precision amplifiers, voltage references, analog-to-digital converters (ADCs), isolation, and microcontroller (MCU) components for a complete sensor to system solution. Explore these signal chains across key vectors: sensor type, sample rate, single-ended or differential sensor input signals, and single-channel or multichannel capability. Applications such as 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 are covered, including sensor biasing.
