I read Datasheet of ADA4622-1/ADA4622-2(Rev. B).

I have a question.

The ADA4622-1/ADA4622-2 are the next generation of the AD820 and the AD822 single-supply, rail-to-rail output (RRO),precision junction field effect transistors (JFET) input op amps…

I'm curious about the shutdown/disable feature of the ADA4622-1.

What is the impedance looking into the ADA4622-1 at its inputs and output when the part is in shutdown?  I like the idea of a circuit like Figure 99 of the datasheet, but what extra load…

I read Datasheet of ADA4622-1/ADA4622-2/ADA4622-4(Rev. D).

I have a question.

IN ELECTRICAL CHARACTERISTICS, VSY = ±15 V  Current Noise Density is 0.8fA/√Hz. (Rev. D | Page 4 of 37)

I See.

IN ELECTRICAL CHARACTERISTICS, VSY = ±5 V  

Hi,

I need some help.

As below picture picked from the datasheet.

The EPAD of 2ch Version(ADA4622-2)  is recommended to connect the EPAD to V+, but the note…

In the Page 1 of the specsheet, the final paragraph reads:

The ADA4622-1 is available in a 5-lead SOT-23 package and an 8-lead LFCSP package

while in the Page 11 of the specsheet, the page shows:

Figure 2 and Figure 3, showing the ADA4622-1 in the SOT…

Hi, I am interested in ADA4622-4 opamp grade B but this grade seems not to be available in the 4 opamp package. It is correct?

Thank you in advance

I wanted to design a filter for the ADA4622-4 using the "Analog Filter Wizard", but the ADA4622-4 was "deprecated".

Please tell me the reason.

Also, ADA4622-1 / -2 is recommended, can I use ADA4622-1 / -2 instead of ADA4622-4.

Best…

I was wondering what the electrical differences were between the LFCSP and SOIC_N packages on the ADA4622-4.  The size of the LFCSP package is elegant, but it also has an EPAD on it which should help with heat dissipation, right?  Are there any other measurable…
