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 | OUTA | output | Output of amplifier A. Can source up to 40 mA typical and sink up to 20 mA typical; short-circuit current to ground ~40 mA typical at V+=15V. |+| 2 | IN-A | input | Inverting input of amplifier A. Input bias current typically 45 nA; input common-mode range extends from ground (V-) up to V+ - 1.5 V. |+| 3 | IN+A | input | Non-inverting input of amplifier A. Input bias current typically 45 nA; input common-mode range from ground to V+ - 1.5 V. |+| 4 | GND | power_in | Negative supply / ground (V-). In single-supply operation this pin is tied to ground; in split-supply operation this is the negative rail (down to -16 V relative to V+). |+| 5 | IN+B | input | Non-inverting input of amplifier B. Input bias current typically 45 nA; input common-mode range from ground to V+ - 1.5 V. |+| 6 | IN-B | input | Inverting input of amplifier B. Input bias current typically 45 nA; input common-mode range from ground to V+ - 1.5 V. |+| 7 | OUTB | output | Output of amplifier B. Can source up to 40 mA typical and sink up to 20 mA typical; short-circuit current to ground ~40 mA typical at V+=15V. |+| 8 | V+ | power_in | Positive supply pin. Single supply 3 V to 32 V, or split supply ±1.5 V to ±16 V. Supply current is typically 1 mA at V+=30V and 0.5 mA at V+=5V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM158DRDR`++## CAD (KiCad official)++- Symbol: `LM158DR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/lm158dr-datasheet.pdf) (11 pp, sha256 `04061385d285d3c0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
