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 | Out | output | Amplifier output. Rail-to-rail output stage; short-circuit current limited to ~10 mA. Voltage swing to within ~18 mV of the rails with RL = 100 kΩ. |+| 2 | V- | power_in | Negative supply rail. Typically tied to ground in single-supply operation. Total supply (V+) - (V-) is 2.1 V to 5.5 V (7.5 V absolute max). |+| 3 | +In | input | Non-inverting input. Rail-to-rail common-mode range from (V-)-0.2 V to (V+)+0.2 V. Input bias current 0.5 pA typical; diode-clamped to supply rails, limit current to 10 mA if driven beyond rails. |+| 4 | -In | input | Inverting input. Rail-to-rail common-mode range from (V-)-0.2 V to (V+)+0.2 V. Input bias current 0.5 pA typical; diode-clamped to supply rails, limit current to 10 mA if driven beyond rails. |+| 5 | V+ | power_in | Positive supply rail. Single-supply operation 2.1 V to 5.5 V referenced to V-. Absolute maximum supply voltage (V+)-(V-) is 7.5 V. Decouple to V- with a local ceramic bypass capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `OPA348M5/TR`+- `OPA348M5M7/TR`+- `OPA348M5M/TR`+- `OPA348M5OPA2348M/TR`+- `OPA348M5OPA2348MM/TR`+- `OPA348M5OPA4348M/TR`+- `OPA348M5OPA4348MT/TR`++## CAD (KiCad official)++- Symbol: `OPA348M5`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/opa348m5-datasheet.pdf) (17 pp, sha256 `9c095a2e63a03e64`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
