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 | NC | unconnected | No internal connection. May be left floating or tied to ground. |+| 2 | INA- | input | Inverting analog input of the op-amp. Rail-to-rail input; input common-mode range −0.1V to VDD+0.1V (spec at VS=5.5V: −0.1 to +5.6V). Absolute max Vss−0.5V to VDD+0.5V. Typical input bias 1pA. |+| 3 | INA+ | input | Non-inverting analog input of the op-amp. Rail-to-rail input; same common-mode range and absolute-max limits as the inverting input. Typical input bias 1pA. |+| 4 | VSS | power_in | Negative supply rail / ground reference. Total supply VDD−VSS from 2.1V to 5.5V (7.5V absolute max). Typically tied to 0V in single-supply operation. |+| 5 | NC | unconnected | No internal connection. May be left floating or tied to ground. |+| 6 | OUT | output | Rail-to-rail op-amp output. Typical output current 53mA (min 35mA over full temp), output swing to within 0.1V of the rails with RL=600Ω or 0.015V with RL=10kΩ. Closed-loop output impedance ~10Ω at 100kHz, G=1. |+| 7 | VDD | power_in | Positive supply rail. Operating range 2.1V to 5.5V referenced to VSS; absolute max VDD−VSS = 7.5V. Typical quiescent current 250µA (max 515µA over full temp). |+| 8 | NC | unconnected | No internal connection. May be left floating or tied to ground. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `OPA314M/TR`+- `OPA314M5/TR`++## CAD (KiCad official)++- Symbol: `OPA314M`+- 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/opa314m-datasheet.pdf) (16 pp, sha256 `52e338c5389f6519`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
