ad5627r, analog output dead, supply and comms ok

Dear colleagues,

we have a problem using the ad5627r that we cannot get to output voltage other than 0V.

- Supply and comms are OK, because we successfully flip Vref on/off via I2C.

- No matter what value we write to DAC, the outputs remain low.

- 3V3 supply

- pins: ~LDAC low, CLR high, ADDR floating.

We are probably forgetting to enable something but cannot figure what...

Any ideas? Thanks!
