If you’re working with precision analog front ends and want an easier way to explore your signal chain ideas, the Signal Chain Designer (SCD) is a great place to start. It’s part of Analog Devices’ Precision Studio and lets you quickly build and simulate complete signal chains. You can check AC response, noise, DC errors, power, input range, and more, all before sending the design to LTspice for deeper analysis.
The tool gives you access to a wide range of components, including SAR and sigma‑delta ADCs, op-amps, differential and instrumentation amplifiers, and references. This makes it easy to try out different architectures and see what works best for your system requirements.
To get the most out of the tool, here's a tech note series that walks through practical workflows, tips, and use cases. Whether you’re just getting into precision signal chains or you’re looking to speed up your design process, these notes give you a helpful starting point as you work with Signal Chain Designer.
