Overview
The OPA445AU is a FET Input Amplifier made by Texas Instruments in a SOIC-8 package with 8 pins. -45V~-10V、10V~45V -55℃~+125℃ 1 10pA 10uV/℃ 15V/us 15mA 15nV/√Hz@1kHz 1mV 23MHz 4.2mA 4pA 95dB Short-Circuit Protection SOIC-8 FET Input Amplifiers ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:OPA445AU, from EasyEDA) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C1346162). 1 open-source board in 1 repository on GitHub use it.

Questions
Is there a KiCad symbol and footprint for the OPA445AU?
Yes. The symbol is EasyEDA_Cloud:OPA445AU 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 OPA445AU?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the OPA445AU datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the OPA445AU?
JLCPCB lists it as part C1346162, with 0 in stock; the sellers' links on this page open their listings.
What can replace the OPA445AU?
Parts like it in the library: the TL072CDT by STMicroelectronics, the TL082CDT by STMicroelectronics, the TL082IDT by STMicroelectronics and the TL072ID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the OPA445AU?
