AD7812 Serial A/D Converter intermittent latch to a constant value

We have developed a Cash Dispenser Controller around BF531 with AD7812 for A/D conversion. We have observed AD7812 output latching to a same value for all 8 channels and can only be recovered by Power recycle. This happens all of a sudden/intermittently. Kindly give us a solution to overcome this problem, and please let us know if you need more information.



Thanks & regards,
