Part Number: ADC12DJ3200

Hello,

Will the ENOB spec on page 16 of the datasheet vary if the device is in dual mode?

Thank you!

Hi Elisha,

Figure 26 on page 30 of the datasheet show the ENOB in Dual mode.

Thanks, Neeraj! Another question though: can we say then that the dual-mode ENOB "slightly varies" compared to single mode...

...because Figure 26 ENOB is slightly higher?

Thanks again!

Hi,

Figure 26 is showing ENOB vs sampling frequency with Fin = 347MHz. Where as Enob shown for Single channel with 347MHz is for fixed sampling frequency (3.2GHz). So if you compare the two, the ENOB for dual channel mode is 9.1 bits where as for single channel is 9bits respectively. Not a huge difference.

Neeraj
