Temperature range is –40°C to +85°C.
Not production tested, guaranteed by design and/or characterization data at release.
Following a self-calibration this error will be in the order of the noise for the programmed gain and update selected. A system calibration will completely remove this error.
Recalibration at any temperature will remove these errors.
I/O Port Logic Levels are with respect to AV
Specifications are subject to change without notice.
