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 | Offset Trim | passive | Offset voltage trim pin. Connect to pin 8 through a 10kΩ potentiometer (1kΩ to 1MΩ range) with wiper to +VCC for ±4mV typical offset null. Leave open if trim is not required. |+| 2 | -In | input | Inverting input of the op-amp. Common-mode input range ±11V (±12.3V typ) at ±15V supplies. Input bias current ±15nA typ, protected by back-to-back diodes (limit differential input current to ±25mA if VDIFF exceeds ±0.7V). |+| 3 | +In | input | Non-inverting input of the op-amp. Common-mode input range ±11V (±12.3V typ) at ±15V supplies. Input bias current ±15nA typ, protected by back-to-back diodes. |+| 4 | -VCC | power_in | Negative supply rail. Rated ±15V, operating range ±4V to ±22V (absolute max ±22V). Quiescent current 3.3mA typ (5.7mA max) at IO = 0mA. |+| 5 | NC | unconnected | No internal connection. May be left floating or tied to a DC potential; no functional effect on the amplifier. |+| 6 | Output | output | Amplifier output. Voltage swing ±12V min (±13.8V typ) into RL ≥ 2kΩ; short-circuit protected with 25mA (60mA max) short-circuit current. Open-loop output resistance 70Ω. |+| 7 | +VCC | power_in | Positive supply rail. Rated ±15V, operating range ±4V to ±22V (absolute max ±22V). Bypass with a local decoupling capacitor to ground. |+| 8 | Offset Trim | passive | Offset voltage trim pin. Connect to pin 1 through a 10kΩ potentiometer with wiper to +VCC. Nulling large system offsets via this pin degrades drift by ~3.3µV/°C per mV of trim. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Amplifiers/Comparators |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `OPA37GU`+- `OPA37GU.B`+- `OPA37GU/2K5`+- `OPA37GU/2K5.B`+- `OPA37GP`+- `OPA37GP.A`+- `OPA37GPG4`++## CAD (KiCad official)++- Symbol: `OPA37GU`+- 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:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/opa37) (None pp, sha256 `a7ea3476fdb58052`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
