AN-342: Analog Signal-Handling for High Speed and Accuracy
A comprehensive guide on analog signal handling, focusing on PCB layout, grounding, and decoupling for high-speed and high-precision electronic designs.
Overview
This application note provides detailed technical guidance for managing analog signals in circuits requiring both high speed and high accuracy. It covers essential design practices including PC board layout strategies, effective grounding techniques, and power supply decoupling to minimize noise and interference. The document highlights the use of high-performance components such as the AD542 and AD544 BiFET op-amps, AD524 and AD624 instrumentation amplifiers, and the AD574 12-bit A/D converter with the AD581 voltage reference. Practical advice is offered on reducing parasitic effects and preserving signal integrity in complex mixed-signal environments.
