System Design Made Simple with National's EMI Hardened Amplifiers

Presentation (pdf)

Designers for data acquisition systems are always facing new challenges from complex noise sources inside and outside of the systems. A lot of time and efforts have to be spent on removing the noise captured from various components of the data acquisition process: Operational Amplifiers, Analog to Digital Converters, Power lines and Digital Communication Interface and so on. In this webinar, we will share the techniques and solutions with design engineers on how to improve noise rejection, especially the EMI from the working environment of devices, e.g. Cell phone Signal, UHF, VHF etc. We will also discuss from concept to real application our EMI rejection solution and how this solution simplifies data acquisition system designs.

Topics covered in this online seminar include:

• Effect of EMI on Data Acquisition Systems
  • Effect of EMI on the overall system performance
  • Where does EMI enter the system
  • Overall system sensitivity for EMI
• Improved EMI robustness through EMI hardened op amps
  • Effect of EMI on op amp performance
  • EMIRR parameter
  • Measuring EMIRR
• Application examples
• EMI hardened products
