Is there a KiCad symbol and footprint for the ADS1281IPW?
Yes. The symbol is Analog & Interface:ADS1281 and the footprint Package_SO:TSSOP-24_4.4x7.8mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ADS1281IPW?
TSSOP-24, with 24 pins. Its footprint is drawn on this page.
Where is the ADS1281IPW datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the ADS1281IPW?
JLCPCB lists it as part C2670771, with 185 in stock; the sellers' links on this page open their listings.
What can replace the ADS1281IPW?
Parts like it in the library: the AD7192BRUZ-REEL by Analog Devices, the AD7795BRUZ-REEL by Analog Devices, the ADC08100CIMTCX by Texas Instruments and the ADS8331IPW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
