This is an ADS1298 breakout board. It can also be used with the ADS1294 and ADS1296.
If you are looking for a full Arduino shield with analog input capability, you might be interested in the HackEEG Shield instead. The HackEEG shield is compatible with the ADS1298 or ADS1299.
The ADS1298 is an 8 channel ADC chip with SPI interface, meant for ECG and EEG:

The breakout board needs +5v input, and provides clean analog and digital power, along with some minimal support circuitry.
Most of the ADS1298's pins are available on the two 20-pin headers.
This board is meant for basic system debugging - electrode circuitry for EEG or ECG is not provided, just access to the chip's differential input pins.
v0.1 of the board has been made and is in testing; v0.2 of the board has not been made yet, and is development.
There is an Arduino Due pinout diagram in docs/arduino_pinout_diagram.png. Refer to that when making the wiring connections. There are also a couple of photos.
ADS1298-breakout pin - Arduino Due pin (SAM3X8E pin)
SPI OUT (MISO) - SPI Header 1 (108)
SPI IN (MOSI) - SPI Header 4 (109)
SCK - SPI Header 3 (11)
GND - SPI Header 6
5V - SPI Header 2

The Arduino Due driver software for this board can be found in the ADS129x-tools github repository.
If you have questions, comments, or improvements, I would love to know them!
