Re: How to fix output value after come back power down state on AD9747?

Hi Tatsuya –

When the AD9747 is powered down by setting SDO high in PIN mode the 8 registers between the P1D and P2D input busses and the analog DAC cores are unknown. There is no mechanism to set the input to the DAC to zero other than writing to P1D/P2D with 8 consecutive clock cycles after power up.

Thanks,

Larry
