Description Of Change
Reason For Change
Anticipated impact of the change (positive or negative) on fit, form, function & reliability
Product Identification (this section will describe how to identify the changed material)
Summary of Supporting Information
Revision to datasheets to reflect current silicon performance: AD7682, AD7689 and AD7949
An improvement is being made to the startup circuitry design. In addition, the AD7682/AD7689/AD7949 datasheets have been revised to reflect the improved
performance as outlined in the attached.
To improve the power up sequencing (which now removes a stipulation the CNV pin must be held LOW at power up) along with improvements to the gain,
offset and other specifications.
Aside from the increased offset match and gain error match (from 2LSBs to 4LSBs), the new material will meet or exceed the performance of the existing
material. There will be no negative impact to form, fit, function and reliability.
Date codes following and including 0840
Qualification has been performed, see attached reliability report. For summary of datasheet changes, see datasheet change attachment.
