Other Parts Discussed in Thread: ADS7954

Hi all,
Please let us know about ADS7954.
We know must have the three voltage inputs for this device.
+VA, Vref, and +VBD.
Does this device have a power-on sequence?

Hello Nagai-san,

Ideally both supplies ramp up concurrently with the only requirement that the (+VA) be always greater than or equal to (+VBD).

Hope this helps.

Best regards,

Jose

Hi Jose,
Thank you for reply. Power sequence is not?
