Class-AB NPN output stage; short-circuit current ±37 mA typ; output swing +13.9 V / −13.9 V into 2 kΩ at ±15 V supply. |+| 2 | IN1- | input | Amplifier 1 inverting input. Bipolar input, 300 nA typ bias current, 16 MΩ differential input resistance. ESD-protected via input diodes. |+| 3 | IN1+ | input | Amplifier 1 non-inverting input. Common-mode range extends from VEE to (VCC − 1.8 V). |+| 4 | VCC | power_in | Positive supply. +3.0 V to +36 V single-supply, or +1.5 V to +18 V in split-supply configuration. Total VCC-to-VEE must not exceed +36 V. |+| 5 | IN2+ | input | Amplifier 2 non-inverting input. Bipolar input; input voltage must not exceed VCC or VEE. |+| 6 | IN2- | input | Amplifier 2 inverting input. 300 nA typ bias current; 3.0 nA typ input offset current. |+| 7 | OUT2 | output | Amplifier 2 output. Unity-gain stable with capacitive loads up to 500 pF. |+| 8 | OUT3 | output | Amplifier 3 output. Class-AB NPN output stage with symmetrical source/sink; output swing +14.1 V / −14.6 V typical. |+| 9 | IN3- | input | Amplifier 3 inverting input. |+| 10 | IN3+ | input | Amplifier 3 non-inverting input. |+| 11 | VEE | power_in | Negative supply (or GND for single-supply operation). Tie to 0 V for single-supply use, or to negative rail (down to −18 V) for split-supply operation. |+| 12 | IN4+ | input | Amplifier 4 non-inverting input. |+| 13 | IN4- | input | Amplifier 4 inverting input. |+| 14 | OUT4 | output | Amplifier 4 output. Low open-loop output impedance (~35 Ω at 6 MHz). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-14 |+| Category | Op-amp/Cmp |+| Pins | 14 |++## Ordering variants++- `MC33274ADR2GMC33274ADG`+- `MC33274ADR2G`+- `MC33274ADR2GNCV33274ADG`+- `MC33274ADR2GNCV33274ADR2G`+- `MC33274ADR2GMC33274APG`+- `MC33274ADR2GNCV33274APG`+- `MC33274ADR2GMC33274ADTBG`+- `MC33274ADR2GNCV33274ADTBG`+- `MC33274ADR2GMC33272ADG`+- `MC33274ADR2GMC33272ADR2G`+- `MC33274ADR2GNCV33272ADR2G`+- `MC33274ADR2GMC33272APG`++## CAD (KiCad official)++- Symbol: `MC33274ADR2G`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOIC-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/mc33274a-d.pdf) (16 pp, sha256 `d10ac1a1a835b1ee`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
