The precision wide bandwidth signal chains bring the insight and flexibility needed to optimize application specific parameters for measurement and drive solutions. While ensuring the necessary accuracy, this fast sampling rate signal chain is ideal for considerations between AC and DC precision and has the required wide bandwidth for measurement or signal generation (DC to 1 MHz). With precision wide bandwidth, easily create a solution targeting your most important specifications, whether for measurement noise (SNR), DC linearity, settling time performance, closed-loop or measurement latency, or total harmonic distortion (THD).

Analog Devices’ precision wide bandwidth signal chains combine 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.

Find solutions to tweak specifications ranging from step size to signal amplitude for applications ranging from hardware in the loop (HiL) and non-destructive test, to the light intensity precision needed for a scanning electron microscope (SEM) or flow cytometry.
