Overview

The OPA2991ID is an operational Amplifier made by Texas Instruments in a SOIC-8 package with 8 pins. -20V~-1.35V、1.35V~20V -40℃~+125℃ 10.8nV/√Hz@1kHz 10pA 10pA 125uV 130dB 2 2.7V~40V 21V/us 300nV/℃ 4.5MHz 560uA 75mA Enable/shutdown function、EMI filtering/RF suppression Rail-to-Rail Input, Rail-to-Rail Output SOIC-8 Operational Amplifier ROHS.

PCBKit's library has its KiCad symbol (Operational Amplifiers:Operational Amplifier x2 Type1 [alt], from CERN's library) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 165 are in stock at JLCPCB (part C2878324). 1 open-source board in 1 repository on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the OPA2991ID?

Yes. The symbol is Operational Amplifiers:Operational Amplifier x2 Type1 [alt] 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 OPA2991ID?

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

Where is the OPA2991ID datasheet?

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

Where can I order the OPA2991ID?

JLCPCB lists it as part C2878324, with 165 in stock; the sellers' links on this page open their listings.

What can replace the OPA2991ID?

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.

Which open-source boards use the OPA2991ID?

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