LMP2231BMFE

Texas Instruments · Precision Op Amps · SOT-23-5

LMP2231BMFE from Texas Instruments, in a SOT-23-5. 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 OUT output Rail-to-rail amplifier output that swings to within 15 mV of the supply voltage.
2 V- power_in Negative supply (ground in single-supply use); the input common-mode range extends 200 mV below it, with a 1.6V to 5.5V total supply range.
3 IN+ input Non-inverting CMOS input with about 20 fA input bias current and a common-mode range extending 200 mV below V-.
4 IN- input Inverting CMOS input with about 20 fA input bias current and a maximum offset voltage of 150 µV.
5 V+ power_in Positive supply, operating range 1.6V to 5.5V relative to V-.

CAD (KiCad official)

  • Symbol: LMP2231BMFE
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: lmp2231bmfe-etched.step / lmp2231bmfe-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lmp2231bmfe.step / lmp2231bmfe.glb are the bare package body.
