ADS42LB69: Does this chip have a SINAD vs Input Frequency vs ENOB graph?

Zhan Cheng Ng

Part Number: ADS42LB69

Hi,

I would like to understand what is the enob and sinad I will be having from this chip if I'm using at frequencies 500MHz and above.

Does anyone has a plot like that?

Here is an example for chip AD9226:

Please refer to page 5.

Thank you.

Hi Zhan Cheng Ng,

The datasheet does not give any information for input frequencies above 300 MHz (page 18 of datasheet

)

The ENOB at 300 MHz is (72.2(SNR)-1.76)/6.02 = 11.70 LSBs.

I will look further at whether or not this data can be obtained, and get back with you soon.

Best Regards,

Dan
