ADC16DX370: Frequency response of ADC16DX370RMET, down to DC ?

h m

Part Number: ADC16DX370

Tool/software:

Hi, I have a question regarding the input frequency response bandwidth of ADC16DX370RMET. The plots in the datasheet all stops at 10MHz. Does that suggest the frequency response does not go down to the actual DC like the regular ADC's do ? In my application where I plan to use this adc for, the input signal is DC, am I mistaken ? Thanks.

Hi,

Yes, the ADC will work at DC. Typically plots stop at 10MHz as the general market for an ADC like this is a frequency domain application at higher IFs.

HM,

There is no lower frequency limit. You can DC couple this ADC so long as the output common mode of the ADC driver meets the ADC common mode requirements. See section 9.1.1.4 Driving the Analog Input for more details.

Thanks, Chase
