I notice for ADR431BRMZ that the datasheet says the package for this part
should be an 8-pin SOIC_N, but the website says it’s an 8-pin MSOP.
There is a mistake in the datasheet order guide for ADR431BRMZ-R7.
The part number ADR431 B RM Z -R7 breaks down into the following format:
Package type: RM
RoHS compliant: Z
Reel size: R7
The package type indicator "RM" indicates that the package is 8-lead MSOP
So therefore the order guide is incorrect as it lists the package type as
A request has been made to the ADR Product line Engineer to make a correction
to the datasheet order guide at the next available opportunity.
