**Texas Instruments** · Operational Amplifier · TSSOP-14

LP324MTX from Texas Instruments, in a TSSOP-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 | OUT A | output | Output of amplifier A, placed at a package corner. |
| 2 | IN A- | input | Inverting input of amplifier A, adjacent to its output. |
| 3 | IN A+ | input | Non-inverting input of amplifier A, with common-mode range that includes ground. |
| 4 | V+ | power_in | Positive supply, 3V to 32V for the LP324-N (absolute maximum 32V). |
| 5 | IN B+ | input | Non-inverting input of amplifier B, with common-mode range that includes ground. |
| 6 | IN B- | input | Inverting input of amplifier B, adjacent to its output. |
| 7 | OUT B | output | Output of amplifier B, placed at a package corner. |
| 8 | OUT C | output | Output of amplifier C, placed at a package corner. |
| 9 | IN C- | input | Inverting input of amplifier C, adjacent to its output. |
| 10 | IN C+ | input | Non-inverting input of amplifier C, with common-mode range that includes ground. |
| 11 | V-/GND | power_in | Negative supply or ground; inputs must not go more than 0.3V below this pin. |
| 12 | IN D+ | input | Non-inverting input of amplifier D, with common-mode range that includes ground. |
| 13 | IN D- | input | Inverting input of amplifier D, adjacent to its output. |
| 14 | OUT D | output | Output of amplifier D, placed at a package corner. |

## CAD (KiCad official)

- Symbol: `LP324MTX`
- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`
- 3D model: TSSOP-14 (KiCad packages3D, STEP)
- 3D model files: `lp324mtx-etched.step` / `lp324mtx-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lp324mtx.step` / `lp324mtx.glb` are the bare package body.
