Is there a KiCad symbol and footprint for the OPA548T?
Yes. The symbol is Operational Amplifiers:OPA548 [alt] and the footprint ICs And Semiconductors THD:TO-220-7-V, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the OPA548T?
TO-220-7, with 7 pins. Its footprint is drawn on this page.
Where is the OPA548T datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the OPA548T?
JLCPCB lists it as part C138712, with 14 in stock; the sellers' links on this page open their listings.
What can replace the OPA548T?
Parts like it in the library: the PA75CX by Apex Microtechnology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the OPA548T?
7 boards in 7 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
