ADC32RF44: Output Data Format

Alpha H

Part Number: ADC32RF44

Hi Jim/Rob,

Quick question for you guys, what is the format of the output data from the ADC32RF44? (2's complement, offset binary, etc)?

Thanks,

AH,

By default, the output data is 2's comp. It can be switched to offset binary with a register write.

Regards,

Jim

Hi Jim,

Another follow up question for you! If a balun is connected directly to the analog input pins, it looks like the polarity would be swapped. Is there a way to invert the polarity? I saw that changing Register 017h changes the polarity of the output JESD lanes, but nothing for the analog input.

Thanks,

Hi AH,

I'm checking with design if there is a programmable invert for analog input. WIll get back to you ASAP.

Vijay

Hi AH,

Unfortunately, there's no option inside ADC32RFxx to invert analog input polarity.
