AD8556 split power supply

Category: Hardware
Product Number: AD8556

Hi everyone,

I am using AD8556 (LFCSP_WQ) in a AFE with a split power supply of +/-2.5V.

The datasheet does not refer to the pins DVSS (13) & DVDD (15) when using a split power supply.

The digital stages of the AD8556 are supposed to interact with a micro-controller that works with a single supply of +3.3V.

How should i connect the pins of the digital stages so that the IC can be programmed by the uC?

Also the EPAD connection is supposed to be tied to DVss (pin 13) as per page 8 of the datasheet. Does that hold true when dealing with a split power supply of +/-2.5V? Shouldn't i connect it to system GND?

Any help will be highly appreciated.

Thanks in advance.

Regards

Manos
