LMH6523: LMH6523

Young Kim

Part Number: LMH6523
Other Parts Discussed in Thread: OPA615, LMH6881, TINA-TI

Hi,

I converted LMH6523 to general PSPICE model as per 5 easy steps TI instruction. But when I run PSPICE I had error message. I copied that below. Please check it out and inform me how to fix it.

Thanks,

Young

Hello Young,

I've attached a working pspice project for the LMH6523. There a few steps missing from that video that highlight how to actually use the .cir file in Pspice. Please use the steps highlighted in this guide:

Hello Hasan,

Thanks for the prompt response.

I tried to open the working project you sent me but I couldn't. The error message ' The Pspice COM Wrapper error has occurred.' popped up. I don't know how to fix this. Any Idea?

Thanks,

Young

Hi Young,

why not running the LMH6523 TINA-TI Reference Design

TINA-TI is a free simulator and can be downloaded here:

Hello Young,

I tried opening the project straight from the zip file after extracting with no issues. I looked up the error and it looks like the issue stems from Pspice itself, I would suggest trying to reinstall the software.

Best,

Hasan Babiker
