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 | OUT1 | output | Output of amplifier 1. Class-AB NPN output stage capable of driving 600 Ω loads with output swing typically ±13.6 V on ±15 V supplies. Short-circuit source/sink current typ ±80/±100 mA. |+| 2 | IN1- | input | Inverting input of amplifier 1. High-impedance PNP input (Rin ≈ 200 kΩ differential); input bias current typ 100 nA, offset current typ 5.0 nA. Common-mode input range typ −14 V to +14 V on ±15 V rails. |+| 3 | IN1+ | input | Non-inverting input of amplifier 1. High-impedance PNP input matched to IN1−; ESD-clamped for ruggedness without affecting device performance. |+| 4 | VEE | power_in | Negative supply rail. Split-supply range −2.0 V to −18 V (±2.0 V to ±18 V dual-supply operation). Absolute maximum VCC to VEE = 36 V. |+| 5 | IN2+ | input | Non-inverting input of amplifier 2. High-impedance PNP input; identical characteristics to IN1+. |+| 6 | IN2- | input | Inverting input of amplifier 2. High-impedance PNP input matched to IN2+; input bias current typ 100 nA. |+| 7 | OUT2 | output | Output of amplifier 2. Class-AB NPN output stage; drives 600 Ω loads with ±13.6 V swing typ on ±15 V supplies. |+| 8 | VCC | power_in | Positive supply rail. Split-supply range +2.0 V to +18 V (±2.0 V to ±18 V dual-supply operation). Total quiescent current typ 420 µA per amplifier (max 1.4 mA for dual at 25°C). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `MC33178DR2GD`+- `MC33178DR2GDG`+- `MC33178DR2GDR2`+- `MC33178DR2GDR2G`+- `MC33178DR2GP`+- `MC33178DR2GPG`+- `MC33178DR2GDMR2`+- `MC33178DR2GDMR2G`+- `MC33178DR2GD`+- `MC33178DR2GDG`+- `MC33178DR2GDR2`+- `MC33178DR2GDR2G`+- `MC33178DR2GP`+- `MC33178DR2GPG`+- `MC33178DR2GDTBR2G`++## CAD (KiCad official)++- Symbol: `MC33178DR2G`+- 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:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/mc33178-d.pdf) (19 pp, sha256 `e9500a8ace2effd1`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
