Is there a KiCad symbol and footprint for the AD156A4?
Yes. The symbol is EasyEDA_Cloud:AD156A4 and the footprint EasyEDA_Cloud:WQFN-32_L4.0-W4.0-P0.40-TL-EP2.7, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the AD156A4?
QFN-32(4x4), with 33 pins. Its footprint is drawn on this page.
Where is the AD156A4 datasheet?
JieLi Tech publishes it: the Datasheet link on this page opens it.
Where can I order the AD156A4?
JLCPCB lists it as part C22440795, with 839 in stock; the sellers' links on this page open their listings.
What can replace the AD156A4?
Parts like it in the library: the HT66L2550A-32QFN by Holtek Semicon. Check their datasheets: a part that fits the footprint may still differ in its ratings.
