Pin Function Grouping

A

adrian95

Looking at the datasheet of this component, can you group together pins by their functions? for example for Power, 3v3, gnd_1 gnd_2 etc
NOTE: If you group them, can you not add the same pin if you already added them in a group? You should know which pin function is common for its function

flux

Yes — for MAX98357AETE+T, I’d group each pin exactly once like this:

Table

Functional groupPins
Power7 VDD, 8 VDD
Ground3 GND, 11 GND, 15 GND, EP Exposed Pad
Digital Audio Input / I²S-PCM1 DIN, 14 LRCLK, 16 BCLK
Configuration / Control2 GAIN_SLOT, 4 SD_MODE
Speaker Output9 OUTP, 10 OUTN
No Connect5 N.C., 6 N.C., 12 N.C., 13 N.C.
This keeps every datasheet pin in one group only; for Flux pin grouping, VDD-type pins belong under Power, GND/exposed pad under Ground, serial audio pins under Communication/Digital Audio, control/configuration pins under Control, OUTP/OUTN under Output, and N.C. pins under No Connect.
