Is there a KiCad symbol and footprint for the AD7888AR?
Yes. The symbol is Analog & Interface:AD7888 and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the AD7888AR?
SOIC-16, with 16 pins. Its footprint is drawn on this page.
Where is the AD7888AR datasheet?
Analog Devices publishes it: the Datasheet link on this page opens it.
Where can I order the AD7888AR?
JLCPCB lists it as part C7455556, with 0 in stock; the sellers' links on this page open their listings.
What can replace the AD7888AR?
Parts like it in the library: the HX711 by Avia Semicon, the NAU7802SGI by Nuvoton Tech, the MCP3008-I/SL by Microchip Technology and the HX717 by Avia Semicon. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the AD7888AR?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
