PGA280 Offset

Other Parts Discussed in Thread: PGA280

Hello,

I'm using a PGA280 and I have some trouble finding the offset for all available gain...

In the datasheet we can find th offset for a gain of 1V/V and 128V/V but nothing else?! And the offset seams to be very different from one gain to another!

Thank you for your answers

    Hi,

    I scoured the PGA280 data-sheet and didn't find the information either. I am checking with the off-site design group to see if they have any voltage offset vs. gain information that they might share.

    I'll let you know if they can provide any data. It may be a few days before I have a response.

    Hi,

    I've received a offset (RTI) vs. gain plot taken from the PGA280 characterization. The data which shows mean, maximum and minimum offset values by gain for a particular characterization lot. The minimum and maximum values only a apply to this lot and are not universal specifications applicable to all PGA280 lots.
