INA117KU from Texas Instruments, in a SOIC-8. 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 | RefB | input | Reference voltage input B; applies −19× weighting coefficient to output through transfer function V₀ = V₃ − V₂ + 20×V₅ − 19×V₁. |
| 2 | -In | input | Inverting input of differential amplifier; differential impedance 800kΩ, common-mode impedance 200-400kΩ; accepts ±10V differential and ±200V common-mode voltage. |
| 3 | +In | input | Non-inverting input of differential amplifier; differential impedance 800kΩ, common-mode impedance 200-400kΩ; accepts ±10V differential and ±200V common-mode voltage. |
| 4 | V- | power_in | Negative power supply for dual-supply operation; recommended ±5V to ±18V, absolute maximum ±22V. |
| 5 | RefA | input | Reference voltage input A; applies +20× weighting coefficient to output through transfer function V₀ = V₃ − V₂ + 20×V₅ − 19×V₁. |
| 6 | Output | output | Differential amplifier output with unity gain; output impedance 0.01Ω, typical output voltage range 10-13.7V. |
| 7 | V+ | power_in | Positive power supply for dual-supply operation; recommended ±5V to ±18V, absolute maximum ±22V. |
| 8 | NC | unconnected | No internal connection; may be grounded or left open without affecting circuit operation. |
