Analog Devices, Inc. (ADI)’s precision low power signal chains offer key differentiation for low power measurement applications. They prioritize overall power utilization while ensuring key information and insights are quickly and reliably transformed from their analog signal to their digital representation.
These signal chain solutions are ideal for applications that are battery-powered or where there is a sensitivity to power dissipation. Key vectors such as precision performance, size, and ease of use have all been considered, in addition to prioritizing power-saving techniques to achieve even longer operating time. They can be scaled from single channel to support multiple measurements if required. ADI also offers integrated solutions that not only take on signal conditioning and measurement, but can also be used to bias and excite external sensors where needed.
ADI’s precision low power signal chains combine precision amplifiers, voltage references, analog-to-digital converters (ADCs), and isolation products. Explore our configurable precision low power solutions for applications such as portable VSM, wireless environmental monitoring (gas, CbM, pH, and temperature), and industrial uses such as intelligent flow, where low power is a key requirement. System designers can confidently build a solution that is optimized for their most important requirements.
