Calculate min input power level of ADC

[demirayar]

Hi everyone,

I want to learn the minimum input power level for ADS800 analog to digital converter @5Mhz input signal. I looked at datasheet but couldn't find. Can anyone help me how it can be computed?

The ADC has a high impedance input, so sensitivity would be calculated in voltage rather than power units. If you refer to the Fig. 9 datasheet schematic with 50 ohm termination, full scale input power is about +16 dBm, "minimum input power" depending on intended SNR.
