LM2902PWR

Texas Instruments · Operational Amplifier · TSSOP-14

LM2902PWR from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1OUT output Output of op-amp 1. Class-AB output stage; output short-circuit to ground is unlimited at TA = 25°C, VCC <= 15V.
2 1IN- input Inverting (negative) input of op-amp 1. Common-mode input range includes V- (ground); low input bias current (typ 20nA).
3 1IN+ input Non-inverting (positive) input of op-amp 1. Common-mode input range includes V- (ground).
4 VCC+ power_in Positive (highest) supply rail. LM2902: 3V to 26V (absolute max 26V). Shared across all four amplifiers.
5 2IN+ input Non-inverting (positive) input of op-amp 2. Common-mode input range includes V- (ground).
6 2IN- input Inverting (negative) input of op-amp 2.
7 2OUT output Output of op-amp 2.
8 3OUT output Output of op-amp 3.
9 3IN- input Inverting (negative) input of op-amp 3.
10 3IN+ input Non-inverting (positive) input of op-amp 3.
11 VCC- power_in Negative (lowest) supply rail, or ground for single-supply operation. Common-mode input range includes this rail.
12 4IN+ input Non-inverting (positive) input of op-amp 4.
13 4IN- input Inverting (negative) input of op-amp 4.
14 4OUT output Output of op-amp 4.

CAD (KiCad official)

  • Symbol: LM2902PWR
  • Footprint: Package_SO:TSSOP-14_4.4x5mm_P0.65mm
  • 3D model: TSSOP-14 (KiCad packages3D, STEP)
  • 3D model files: lm2902pwr-etched.step / lm2902pwr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm2902pwr.step / lm2902pwr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm2902pwr.step 194 KB You want the bare part, or you mark your own boards.
lm2902pwr-etched.step 2.3 MB You want the part with LM2902PWR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 567 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (65 pp, sha256 a4eda7c3a0236e96, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
