AD7765 Count to voltage Conversion ?

Hi !

I am using AD7765 EVAL Board with Artix-7 FPGA board. 

MCLK - 40MHz on board crystal available on EVAL AD7765 Board.

DEC Rate - 128x with ODR = 156.2kHz.

I am giving 1VDC input from voltage source to Pin 2 (+ve) and Pin 3 (-ve) of J1 Connector on AD7765 EVAL board.

I am getting 10 samples, 24 bit count like this: 

1574208
1574021
1573936
1573951
1573995
1573935
1574004
1574011
1573954
1573981

How do I convert this count to get input voltage?

ADC is working in Normal mode with default gain of 1.25.

Thanks
