Hi Sushmita,

No, it is not necessary to connect DRDY to an Arduino Uno pin.

As stated in section 9.5.1 of the datasheet: The serial interface consists of five control lines: CS, SCLK, DIN, DOUT/DRDY, and DRDY but can be used with only four or even three control signals. If the ADS124S08 or ADS124S06 is the only device connected to the SPI bus, then the CS input can be tied low so that only SCLK, DIN, and DOUT/DRDY are required to communicate with the device.
