Added ADI ADA4691-x and ADI ADA4692-x family
This MR adds the ADI ADA4691-x and the ADA4692-x family. The difference between both families is the added shutdown pin for the ADA4691-x. I have added new footprints were required. The MRs can be found in the relevant sections.
This MR deliberately violates KLC S3.1, because the third symbol (symbol C) of the dual op amps is composed of only the power connectors, which are off-center. Additionally KLC S3.2 is stretched a bit, because the SHDN pin is printed in a smaller font to fit inside the opamp symbol.
ADA4691-2ACBZ
Symbol
This device requires a new symbol, because the WLCSP-9 package has a unique pin layout.
Pins
Properties
I have added some basic properties and the shutdown feature to distinguish it from the ADA4692-2.
The footprint is not available in the standard library, so I added it to the footprint generator and opened an MR at kicad-footprint-generator!1080 (merged) and kicad-footprints!3573 (merged).
The new footprint is called WLCSP-9_1.21x2.1.22mm_P0.4mm
ADA4691-2ACPZ
Symbol
This device requires a new symbol, because the LFCSP-10 package has a unique pin layout.
Pins
Properties
I have added some basic properties and the shutdown feature to distinguish it from the ADA4692-2.
Footprint
The footprint is not available in the standard library, so I added it to the footprint generator and opened an MR at kicad-footprint-generator!1079 (merged) and kicad-footprints!3572 (merged).
The new footprint is called LFCSP-10_2x2mm_P0.5mm
ADA4691-4ACPZ
Symbol
This opamp uses the same pinout as the TLV9064xRTE symbol, but I did not add it as a derived symbol, because the TLV9064xRTE symbol has the inverting and non-inverting pins swapped, i.e. the inverting pin is drawn on top instead of the default non-inverting pin.
Pins
Properties
I have added some basic properties and the shutdown feature to distinguish it from the ADA4692-4. Note: The symbol is no longer derived from the TLV9064xRTE, because this symbol has a weird way of drawing the opamp pins.
Footprint
Regarding the footprint, I used the LFCSP-16-1EP_3x3mm_P0.5mm_EP1.6x1.6mm as given in the datasheet and provided by the standard library.
ADA4692-2ACPZ
Symbol
This opamp uses the same pinout as the LM2904 symbol. I therefore added it as a derived symbol.
Pins
Properties
Footprint
Regarding the footprint, I used the LFCSP-8_2x2mm_P0.5mm as given in the datasheet and provided by the standard library.
ADA4692-2ARZ
Symbol
This opamp uses the same pinout as the ADA4692-2ACPZ above. I therefore used the same LM2904 base symbol.
Pins
Properties
Footprint
The footprint I used is the SOIC-8_3.9x4.9mm_P1.27mm as given in the datasheet and provided by the standard library.
ADA4692-4ARUZ
Symbol
This opamp uses the same pinout as the LM2902 symbol. I therefore added it as a derived symbol.
Pins
Properties
Footprint
The footprint I used is the TSSOP-14_4.4x5mm_P0.65mm as given in the datasheet and provided by the standard library.
This merge request has gotten slightly out of hand ;) Initially intended as a quick MR to add the ADA4691-2, it turned into rather big MR including two new footprints and 3D models.
Here is an overview of the MRs involved:
- ADA4691-2ACBZ
- ADA4691-2ACPZ

Provide a URL to a datasheet for the symbol(s) you are contributing -
An example screenshot image is very helpful -
Ensure that the associated footprints match the official footprint library - A new fitting footprint must be submitted if the library does not yet contain one.
-
If there are matching footprint PRs, provide link(s) as appropriate -
Check the output of the automated check scripts - fix any errors as required -
Give a reason behind any intentional library convention rule violation.
