Under non-bridge conditions, usually offset is no more than a few mA. Anything over 30mA stationary would start me worrying, and above 500 mA will become risky A dc-protection usually kicks in somewhere at 1Vdc.
In a bridge configuration, you should be able to balance the dc somehow (never do it with this chipsamp though).
