Class-A/AB output stage capable of sourcing up to ~50mA and sinking a few mA typical; short-circuit current to GND ~40mA. |+| 2 | -IN_A | input | Inverting input of amplifier A. High-impedance PNP input stage, typical input bias current 45nA (max 150nA), input offset current typ 3nA. |+| 3 | +IN_A | input | Non-inverting input of amplifier A. Common-mode input range from 0V (ground) up to V+ - 1.5V; must not go more than 0.3V below ground. |+| 4 | -Vs | power_in | Negative supply / ground. Connect to GND for single-supply operation or to the negative rail for dual-supply operation. Total (V+ - V-) supply range 3V to 25V (abs max 25V). |+| 5 | +IN_B | input | Non-inverting input of amplifier B. Common-mode input range from 0V (ground) up to V+ - 1.5V. |+| 6 | -IN_B | input | Inverting input of amplifier B. PNP input stage, typical input bias 45nA. |+| 7 | OUT_B | output | Output of amplifier B. Class-A/AB output stage; typical source current 50mA, output swing VOH ~23V at V+=25V with RL=2k. |+| 8 | +Vs | power_in | Positive supply pin. Operating range +3V to +25V (single or dual supply, referenced to -Vs). Typical supply current 430uA at V+=5V; absolute maximum (V+ - V-) = 25V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `BL358`+- 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:** [BL Shanghai Belling datasheet](docs/bl358-datasheet.pdf) (7 pp, sha256 `79144bd1de9cce24`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
