PGA281: Using 4 PGA281

Dalton Vono

Part Number: PGA281

Dear Sirs,

I will use 4 PGA281 to amplify 4 different inputs. Can I connect the gain selection pins of all PGA281 together (G0:G4)? And the VOCM pin can I do it too? (like schematic bellow)

Best Regards

Hi Dalton,

Yes, if you plan on setting the gain of all four PGAs to the same setting you may connect the gain selection pins as shown. The Vocm pin may also be connected in this manner.

Regards,

Zach
