ADAR7251

I have several boards using the ADAR7251. If I connect a low level input signal < 40 dB FS to channel 1 and channel 2. I get 0  output data on 1 channel, sometime channel1, sometimes channel 2. Taking the input above - 40dB FS and then back down again, both channels then work fine. Almost like internal digital filters are stuck on 0.

 

Anything I can do to cure this problem ?

 

Many thanks

Chris.
