Schematic Component Verification


Check the schematic component against the datasheet for [MPN]. Assign the correct pin orientation, section, and terminal order for each pin. Place Power pins first and GND pins last. For every section, distribute the pins logically and as evenly as possible between the Left and Right sides of the symbol, so the schematic symbol is balanced and easy to read. Apply the changes directly to the schematic component.
Got it — I’ll include symbol cleanup in the same review: verify against the datasheet, then directly update pin orientation/sections/order with power pins first and grounds last.
I found the official ADI public datasheet and updated the project-level Datasheet URL; ADI’s public PDF is only a summary and says full pin details require NDA, so I’m using the public ADI article/figure plus the existing 49-bump footprint for pin verification and will flag that limitation.

MAX86178 Datasheet Review

Reviewed the MAX86178 part project metadata, 49 schematic terminals, footprint pad count, available project properties, and public datasheet...
Completed the MAX86178 review and applied the symbol metadata updates directly: datasheet URL, manufacturer/type/package metadata, pin descriptions, pin types, sections, orientations, terminal order, and balanced symbol positions for all 49 terminals.
Open items:
  • ADI’s public datasheet does not include the full bump map or detailed pin table; final production verification requires the NDA datasheet or ADI-authorized CAD model.
  • Footprint A1 orientation, D/E axis mapping, and exact land pattern still need NDA/source verification.
