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 | OFFSET_NULL | passive | Offset null pin. Used together with pin 5 and a 10 kΩ potentiometer (wiper tied to V-) to trim the input offset voltage of the op-amp to zero. |+| 2 | IN- | input | Inverting input of the operational amplifier. Differential input voltage rating ±30V; input voltage range typ ±13V at Vs=±15V. Typical input bias current 80 nA, input resistance ~2 MΩ. |+| 3 | IN+ | input | Non-inverting input of the operational amplifier. Differential input voltage rating ±30V; input voltage range typ ±13V at Vs=±15V. Typical input bias current 80 nA, input resistance ~2 MΩ. |+| 4 | V- | power_in | Negative supply rail. Absolute maximum ±18V (total supply). Together with V+ powers the op-amp; typical supply current 1.7 mA. |+| 5 | OFFSET_NULL | passive | Offset null pin. Used together with pin 1 and a 10 kΩ potentiometer (wiper tied to V-) to trim the input offset voltage of the op-amp to zero. |+| 6 | OUT | output | Amplifier output. Class-AB output stage with continuous short-circuit protection (25 mA typical short-circuit current). Output swing ±14V typ at Vs=±15V with RL≥10kΩ. |+| 7 | V+ | power_in | Positive supply rail. Absolute maximum ±18V (total supply). Typical power consumption 50 mW at Vs=±15V. |+| 8 | NC | unconnected | No internal connection. Leave floating or tie to any convenient potential; not used by the die. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM741M/TR`+- `LM741MLM741AM/TR`+- `LM741MLM741N`+- `LM741MLM741AN`+- `LM741MM/TR`+- `LM741MLM741AMM/TR`++## CAD (KiCad official)++- Symbol: `LM741M`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/lm741m-datasheet.pdf) (9 pp, sha256 `2c15bc22a02b633a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
