Questions

Is there a KiCad symbol and footprint for the DDC112U?

Yes. The symbol is EasyEDA_Cloud:DDC112U_1K and the footprint Package_SO:SOIC-28W_7.5x17.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the DDC112U?

SOIC-28-300mil, with 28 pins. Its footprint is drawn on this page.

Where is the DDC112U datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the DDC112U?

JLCPCB lists it as part C1542601, with 43 in stock; the sellers' links on this page open their listings.

What can replace the DDC112U?

Parts like it in the library: the DDC112U/1K by Texas Instruments, the AD9220ARZ-REEL by Analog Devices, the AD9240ASZRL by Analog Devices and the AD9220ARSZ-REEL by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the DDC112U?

3 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
