[Free, June 23 (Tue)] Marubun Technical Seminar: LTspice Hands-on Seminar (Op-Amp Edition)

Electronics trading company Marubun Corporation will hold a free online seminar on Tuesday, June 23, where participants can learn how to verify op-amp stability and noise characteristics using LTspice.

This seminar utilizes the "LTspice" analog circuit simulator provided by Analog Devices. Focusing on a general-purpose op-amp (AD8691), the session will cover checking open-loop gain (AOL) and gain-bandwidth product (GBW), as well as practical simulation analysis methods and improvements for "stability (phase margin)" and "noise," which are common challenges in analog design.

Targeting those who wish to learn LTspice operation, apply it to circuit design, or visually understand op-amp stability and noise characteristics through simulation, the seminar aims to help engineers master analysis skills and improve development efficiency and quality through verification and countermeasures at the design stage.

[Schedule] - 13:40-: Connection test - 14:00-: Opening remarks, AD8691 product overview, and circuit explanation - 14:05-: Checking AOL and GBW - 14:15-: Checking stability - 14:35-: Checking noise - 14:55-: Summary - 15:00-: Closing *Times may shift depending on the day's proceedings.
