Hi everyone

 

It's my first time to use ad7714-5, i connect it as in the datasheet with 2.5 v reference, 5 v supply and 1 MHz crystal, when i power up the circuit the DRDY signal still high and therefore i cannot write any register command of ad7714 , i try this without connecting the ad7714 with any microcontroller, is this case normar ? when the DRDY goes to low so i can write the command and read the output register?

 

 

Thanks for your help
