ADA4857-1 exposed pad

Question

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. 
 Regards Joe

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.
