Clicks, pops and/or pink noise on the analog outputs of the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter?

This could be caused by a couple of scenarios:

A) If the 8824 is configured for the analogue outputs to get their source signal from the ADAT (optical) digital inputs and no signal is present the ADAT chip can act erratically and produce noise and digital garbage.

B) If the 8824 is configured for the analogue outputs to get their source signal from the ADAT (optical) digital inputs and the ADAT is turned off. Always power up ADATs and/or external clocks connected to the ADA 8824 first then power up the 8824 last.
