Questions

Is there a KiCad symbol and footprint for the AD1955ARS?

Yes. The symbol is Audio:AD1955 and the footprint Package_SO:SSOP-28_5.3x10.2mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AD1955ARS?

SSOP-28, with 28 pins. Its footprint is drawn on this page.

Where is the AD1955ARS datasheet?

Analog Devices publishes it: the Datasheet link on this page opens it.

Where can I order the AD1955ARS?

JLCPCB lists it as part C7457365, with 0 in stock; the sellers' links on this page open their listings.

What can replace the AD1955ARS?

Parts like it in the library: the DAC8814IBDB by Texas Instruments, the LTC1668IG#PBF by Analog Devices, the DAC8814ICDB by Texas Instruments and the AD7564BRSZ-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 AD1955ARS?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
