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
…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 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…
Dear all,
I'm considering using ADA4622-2 as an input buffer in a voltage follower configuration for a medical application. Op-amp will be powered in +/-5V and inputs will be connected to a patient through input resistors.
Is there known or foreseeable…
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…
