# LMP2021MAX

**Texas Instruments** · Precision Op Amps · SOIC-8

LMP2021MAX from Texas Instruments, in a SOIC-8. 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 | N/C | unconnected | No internal connection on the D (SOIC-8) package; leave unconnected. |
| 2 | -IN | input | Inverting input; the absolute maximum differential input voltage is VS (the supply span), and all pins must stay between V- − 0.3 V and V+ + 0.3 V. |
| 3 | +IN | input | Non-inverting input; all pins must stay between V- − 0.3 V and V+ + 0.3 V (absolute maximum). |
| 4 | V- | power_in | Negative supply; the supply span VS = V+ − V- is specified at 2.2 V to 5.5 V, with an absolute maximum of 6.0 V. |
| 5 | N/C | unconnected | No internal connection on the D (SOIC-8) package; leave unconnected. |
| 6 | OUT | output | Amplifier output; short-circuit duration to V+ or V- is limited to 5 seconds. |
| 7 | V+ | power_in | Positive supply; the supply span VS = V+ − V- is specified at 2.2 V to 5.5 V, with an absolute maximum of 6.0 V. |
| 8 | N/C | unconnected | No internal connection on the D (SOIC-8) package; leave unconnected. |

## CAD (KiCad official)

- Symbol: `LMP2021MAX`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `lmp2021max-etched.step` / `lmp2021max-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lmp2021max.step` / `lmp2021max.glb` are the bare package body.
