Please let me consult about the LTC2757 glitch.
Even though the UPD pin is in the L state, if the value of DATA I/O is changed,
A glitch occurs at the output when changing the value of the DATA I/O to the output.
Is this normal?
(Other conditions are WR terminal = H, READ terminal = L, SPAN I/O is not changed. S0 = 0, S1 = 1, S2 = 0)
Hi UBOTI
Could you get an OSC capture of the output glitch when changing the DATA on the I/O pins? I've got a hunch this is related to the Digital-to-Analog glitch impulse.
Best regards

Thank you very much for contacting me.
We will send you the waveforms and conditions.
(If you need a circuit diagram, I would like to exchange it other than the web, please tell me your contact information)
Thank you.

Hi UBOTI
You can send the schematic or layout files (if available) to my work email ianvincent.andal@analog.com but let's continue the discussion here. I don't have an eval board with me to test but this seems like D-to-A glitch. Unfortunately, the glitch impulse spec on the ds covers a different procedure.
