Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | RG | passive | Gain-setting resistor pin; an external RG between pins 1 and 8 raises gain above 100 per G = 100 + 250kΩ/RG (250kΩ term accurate to ±40%), and it is left open for G = 100. |+| 2 | V-IN | power_in | Inverting input, protected to ±40V even with no supply present, and it needs a bias current return path. |+| 3 | V+IN | power_in | Non-inverting input, protected to ±40V even with no supply present, and it needs a bias current return path. |+| 4 | V- | power_in | Negative supply, rated for supply voltage up to ±18V (±2.25V to ±18V operating), with a 0.1µF decoupling capacitor recommended. |+| 5 | Ref | input | Output reference terminal, normally grounded, and it must be a low-impedance connection to preserve common-mode rejection (5Ω in series degrades 110dB CMR to about 106dB). |+| 6 | VO | output | Output, VO = 100(V+IN - V-IN) referred to Ref, with stable operation up to 1000pF load and short-circuit current of +20/-15mA. |+| 7 | V+ | power_in | Positive supply, rated for supply voltage up to ±18V (±2.25V to ±18V operating), with a 0.1µF decoupling capacitor recommended. |+| 8 | RG | passive | Gain-setting resistor pin; an external RG between pins 8 and 1 raises gain above 100 per G = 100 + 250kΩ/RG, and it is left open for G = 100. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | PDIP-8 |+| Category | Amplifiers/Comparators |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `INA131AP`+- Footprint: `Package_DIP:DIP-8_W7.62mm`+- 3D model: PDIP-8 (KiCad packages3D, STEP)+- 3D model files: `ina131ap-etched.step` / `ina131ap-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ina131ap.step` / `ina131ap.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/ina131) (13 pp, sha256 `b6c143127ab827ad`, retrieved 2026-10-01, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-4-5-20251001` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
