Good morning. I have a customer inquiring as to how low the freqeuncy of a signal can be to drive the analog inputs of the AD9214-105 and the AD6644-65. He needs to be able to accommodate some signals that will be in the range from 50KHz - 100KHz.
I reviewed your AD8138 and AD9214 schematic blocks. I do not currently have access to a viewer for your Altium Designer file. Maybe you could export to a pdf or take a screen image capture? Are you experiencing a specific issue with your circuit…
I've got this chip AD9211-200 with AD8138 as the ADC driver,actually AD8138 maybe the 2nd choice chip on your recommended ADC driver for AD9211 list,I think it's all OK.
I found AD9211 is a internal bias ADC,and I need the ADC to be good…
