Overview

The OPA277U is an operational Amplifier made by Texas Instruments in a SOIC-8 package with 8 pins. -18V~-2V、2V~18V -40℃~+85℃ 1 140dB 150nV/℃ 1MHz 1nA 20uV 35mA 4nA 790uA 800V/ms 8nV/√Hz@1kHz SOIC-8 Precision Op Amps ROHS.

PCBKit's library has its KiCad symbol (EasyEDA_Cloud:OPA277PA, from EasyEDA) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 8 are in stock at JLCPCB (part C1346182).

Questions

Is there a KiCad symbol and footprint for the OPA277U?

Yes. The symbol is EasyEDA_Cloud:OPA277PA 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 OPA277U?

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

Where is the OPA277U datasheet?

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

Where can I order the OPA277U?

JLCPCB lists it as part C1346182, with 8 in stock; the sellers' links on this page open their listings.

What can replace the OPA277U?

Parts like it in the library: the LM358D by onsemi, the LM2904D by onsemi, the NE5532D by Texas Instruments and the LM358DT by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
