ADA4857-1 exposed pad

Dear Sir/Madam,

The AD4857-1 datasheet specifies that:

"THE EXPOSED PAD MAY BE CONNECTED TO GND OR VS."

Is this +VS or -VS?

I have split supplies.

  • Hello,

    The Exposed Paddle is primarily used for heat dissipation and it is usually connected to the lowest potential.
    For Single supply, your -VS is connected to GND, and this is your lowest potential.
    For Split supply, your -VS is the lowest potential.

    You can check this link to see some advantages of having an Exposed Paddle.

    Thanks.
