Tools & Simulations

Precision ADC Driver Tool

The Precision ADC Driver Tool is a web application that simulates the performance of precision ADC and driver combinations. Potential issues with driver selection, kickback settling, and distortion are flagged, and design tradeoffs can be quickly evaluated. Simulations and calculations include system noise, distortion, and settling of the ADC input

EVAL-FDA-1

Universal Evaluation Board for Single Differential Amplifiers

Product Details

The Universal Differential Amplifier Evaluation Boards can be used to evaluate single, high speed, fully differential amplifiers. The evaluation boards are bare boards that enable users to quickly prototype a variety of differential or single-ended circuits, which minimizes risk and reduces time to market. These boards are all RoHs Compliant. See references below on what board to order by lead count and package.
