1. We have a system where AD7836 DAC is driven by an FPGA. FPGA provides Data and Commands to AD7836.

2. If FPGA is powered and provides Data and Control but AD7836 is not powered, will it cause damage to AD7836

3. In the same system we have ADC AD7865 feeding data to FPGA and getting commands from FPGA. If FPGA is powered and ADC not yet powered will it damage AD7865?

4. This is a separate question: I do not find from data sheet any powering sequence for AD7836 and AD7865. Is there any recommended powering sequence for these devices?
