ADS8681: Gain Error FSR Clarification

Part Number: ADS8681

Tool/software:

Hello,

I would like clarification on the gain error spec of +/- 0.025 %FSR.

Lets take 2 separate cases

1. Unipolar Input Range of 0V to 10.24V.

The gain error at 10.24V input is +/- 0.025% * 10.24V = 2.56mV. I think this is straightforward.

2. Bipolar Input Range of -5.12V to +5.12V.

Is the gain error at 5.12V input also +/- 0.025% * 10.24V (FSR) = 2.56mV?

Thanks,

Stanley
