AD9262 unused pins

coolparam on Sep 25, 2011

Hi,

I am using only one channel of AD9262. What should I do with the unused pins of the other channel, including the data output and the differential analog input pins? Pullup, pulldown, unconnected, grounded ... ?

In addition, can I leave the ORA/ORB pin unconnected if they are not used?

Thank you very much.

Hello,

Using the AD9261 would be the preferred option since this is a single version of AD9262. However, if this is not possible, I would suggest "shorting" the analog inputs (VIN) and leaving the CMOS digital outputs open since the AD9262 does not have allow power-down of one ADC only.
