AD9834 at cold temperature

Hi,

 

I am using an AD9834BRUZ and it runs fine at room temperature.  It's when I get the circuit colder (-35C) is when it starts to misbehaves.  It will sometimes not change the output when commanded through the SPI bus.

 

I have tried an AD9834CRUZ as well and I have the same problem.  I am wondering if you have encountered this and have a suggestion to resolve this.

 

Thanks,

Tehmosp Khan
