LM2901AVQDR

Texas Instruments · Comparators · SOIC-14

LM2901AVQDR from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	OUT1	output	Output pin of the comparator 2 as labeled in the datasheet's pin table; the datasheet notes some manufacturers transpose the channel 1 and 2 names, which is electrically identical.

CAD (KiCad official)

Symbol: LM2901AVQDR
Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
3D model: SOIC-14 (KiCad packages3D, STEP)
3D model files: lm2901avqdr-etched.step / lm2901avqdr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm2901avqdr.step / lm2901avqdr.glb are the bare package body.
