LM7372: Tina Simulation indicates 18V p-p on the output, but getting 17V on my PCB

Lauren Mayfield

Part Number: LM7372

Hi,

Posting this Q on behalf of my customer. Please reach out to me internally once the post is assigned for the schematic/waveforms.

"I am using two LM7372 OPAMP to drive a 50 ohms line.

The attached TINA simulation indicates I should be able to get 18Vp-p on the output.

But in my PCB I get only about 17V. The positive going wave reaches only up to +8V. The negative going wave is okay as it reaches -9V.

What would be causing this?"

Thanks,
Lauren

There was not attached TINA sim - Frequency would help, might be slew limited or clipping.
