AD7294 DAC output spike at startup

Hi,

I have observed that the output DAC pins have as much as a 0.1V spike on powering the 7294 chip. This is a problem as they are controling a high voltage supply and I can't have that spiking from 0 when I power the chip on. Any advice, or is there a proper way to prevent this with correctly setting the power down register when I shut it off?

Thanks
