I am using ADA4930-1YCPZ-R2 part in my design,For designing circuit i am referring UG-889 eval board user guide andit is mention in user guide that at input side decoupling capacitor 10UF at 3528 package.Is it necessary to use this much big package…
I have a single-ended unipolar input signal of 0V to 5V (50 ohms source resistance) connected to the non-inverting input of the ADA4930-1.
The ADA4930-1 is powered by single-supply 5V and has input common-mode voltage range of 0.3V to 2.8V.
I find that ADA4930-1single-supply is 3.3V or 5V in datasheet.So I want to know why the supply is stationary?why not 3.3V to 5V?If this must be stationary 3.3V or 5V,could you give Min and Max of 3.3V and 5V,we only get Typ in datasheet.
I am planning on using AD8336, ADA4930-1 and AD9681.
AD8336 to ADA4930-1 is DC coupled with unipolar signal that has DC offset.
The unipolar signal is connected to the non-inverting input of the ADA4930-1.
What options are available…
What is the output impedance (or model) of ADA4930-1 when switched off using Power-Down pin. Is the impedance defined by output resistors + resistor-feedback network?

Thank you for kind reply.
However, my question is not to compare noise performance between ADA4930 and AD8331.
My question is to compare noise performance between following
1. AD8331(LO mode) -> ADA4930 -> AD9253
2. AD8331(LO mode)
ADA4930-2YCPZ is just the dual version of ADA4930-1YCPZ. These part numbers differ in:
1. # of Channels
3. Thermal Resistance (due package variations)
4. 0.1 dB flatness (table 1, page 3 and figure 17, page 10)
With the parameters enumerated…
