Questions
Is there a KiCad symbol and footprint for the ADR291ER?
Yes. The symbol is EasyEDA_Cloud:GP5040-TC50-SW and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ADR291ER?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the ADR291ER datasheet?
Analog Devices publishes it: the Datasheet link on this page opens it.
Where can I order the ADR291ER?
JLCPCB lists it as part C3680041, with 0 in stock; the sellers' links on this page open their listings.
What can replace the ADR291ER?
Parts like it in the library: the ADR4525BRZ-R7 by Analog Devices, the ADR4525ARZ-R7 by Analog Devices, the ADR421ARZ-REEL7 by Analog Devices and the REF54250CD by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
