Overview

The OPA643UB is an operational Amplifier made by Texas Instruments in a SOIC-8 package with 8 pins. -40℃~+85℃ 1 100nA 16mA 19uA 1V/ns 2.3nV/√Hz@1MHz 3uV/℃ 500uV 65mA 92dB Decompensated stable SOIC-8 Operational Amplifier.

PCBKit's library has its KiCad symbol (EasyEDA_Cloud:OPA643UB, from EasyEDA) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C4369125).

Questions

Is there a KiCad symbol and footprint for the OPA643UB?

Yes. The symbol is EasyEDA_Cloud:OPA643UB and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the OPA643UB?

SOIC-8, with 8 pins. Its footprint is drawn on this page.

Where is the OPA643UB datasheet?

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

Where can I order the OPA643UB?

JLCPCB lists it as part C4369125, with 0 in stock; the sellers' links on this page open their listings.

What can replace the OPA643UB?

Parts like it in the library: the TS922IDT by STMicroelectronics, the LMV358B-SR by 3PEAK, the MC33178D by onsemi and the BUF634AID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
