LTC2325-16 delivers only 15 bits

Hi,

 

i am using LTC2325-16 in CMOS SDR mode. In the datasheet it says: "A 100MHz external clock must be applied at the SCK pin to achieve 5Msps throughput using all four SDO outputs."

But i can't get 16 bits with a 100MHz clock. The LSB is always zero. It seems like the internal logic never presents the LSB. All other bits are fine. Users in a german forum have the same problem. (ADC liefert nur gerade Werte. - Mikrocontroller.net )

 

Is there any solution for the problem?

 

Thank you
