Precision Wide Bandwidth
Analog Devices’ Precision Signal Chains accelerate technology selection and evaluation, providing signal chain options for unique application requirements. Each signal chain brings insight and application knowledge from ADI’s engineers, leveraging their decades of experience and the industry’s leading analog portfolio.
The Precision Wide Bandwidth Signal Chains balance speed with high precision AC/DC measurement and drive performance. Each solution brings together each key stage of the signal chain and can be optimized for a variety of application-specific requirements such as measurement noise (SNR), DC linearity, settling time performance, closed-loop/measurement latency, or total harmonic distortion (THD). For current/voltage measurement applications up to 18-Bit performance is available at 15MSPS sampling frequency. Where current/voltage drive is required, up to 16-Bit performance at 30MSPS update rate is enabled.
These solutions combine ADI's precision amplifiers, voltage references, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), circuit protection and isolation products, allowing system designers to build with confidence a solution that optimizes for their precision and speed requirements.
