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 | VO1 | output | Output of input amplifier A1, which can drive external loads of 25kΩ || 200pF. |+| 2 | Gain Sense1 | input | Gain-sense connection for VO1; pins 2-3 are connected together for G=1 and the 25kΩ feedback path is shorted by tying pins 1-2-3 and 8-14-15 to reduce gain peaking. |+| 3 | RG | passive | Gain-setting resistor terminal; G = 1 + 50kΩ/RG, and it is tied to pin 2 for G=1. |+| 4 | V-IN | power_in | Inverting signal input, individually protected to ±40V and requiring a DC bias-current return path. |+| 5 | V+IN | power_in | Non-inverting signal input, individually protected to ±40V and requiring a DC bias-current return path. |+| 6 | NC | unconnected | No internal connection. |+| 7 | V- | power_in | Negative power supply; the device operates from ±2.25V to ±18V. |+| 8 | VO2 | output | Output of input amplifier A2, which can drive external loads of 25kΩ || 200pF. |+| 9 | NC | unconnected | No internal connection. |+| 10 | Ref | input | Output reference terminal, normally grounded, which must be low impedance for good common-mode rejection (5Ω in series degrades CMR to about 80dB at G=1). |+| 11 | VO | output | Output of the output amplifier A3, which is stable with load capacitance up to 1000pF and has a short-circuit current of +20/-15mA. |+| 12 | Feedback | input | Output sense feedback connection that must be connected to the output terminal (pin 11) for proper operation. |+| 13 | V+ | power_in | Positive power supply; the device operates from ±2.25V to ±18V. |+| 14 | RG | passive | Second gain-setting resistor terminal, paired with pin 3 for the external RG; tied to pin 15 for G=1. |+| 15 | Gain Sense2 | input | Gain-sense connection for VO2; pins 14-15 are connected together for G=1. |+| 16 | NC | unconnected | No internal connection. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16-300mil |+| Category | Amplifiers/Comparators |+| Pins | 16 |++## CAD (KiCad official)++- Symbol: `INA115AU`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16-300mil (KiCad packages3D, STEP)+- 3D model files: `ina115au-etched.step` / `ina115au-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ina115au.step` / `ina115au.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/ina115) (17 pp, sha256 `bd22feb16c03abae`, retrieved 2026-10-08, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-5-5` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
