# INA217AIDWR

**Texas Instruments** · Instrumentation Amplifiers · SOIC-16-300mil

INA217AIDWR from Texas Instruments, in a SOIC-16-300mil. 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 | NC | unconnected | No internal connection. |
| 2 | RG1 | input | Gain-setting pin; for gains greater than 1, connect an external resistor between pins 2 and 15. |
| 3 | NC | unconnected | No internal connection. |
| 4 | VIN- | power_in | Inverting input. |
| 5 | VIN+ | power_in | Non-inverting input. |
| 6 | NC | unconnected | No internal connection. |
| 7 | V- | power_in | Negative power supply; the total V+ to V- supply is specified from ±4.5 V to ±18 V. |
| 8 | NC | unconnected | No internal connection. |
| 9 | NC | unconnected | No internal connection. |
| 10 | REF | input | Reference input for the output; it should be a low-impedance connection, since a few ohms in series degrade common-mode rejection. |
| 11 | VOUT | output | Amplifier output. |
| 12 | NC | unconnected | No internal connection. |
| 13 | V+ | power_in | Positive power supply; the total V+ to V- supply is specified from ±4.5 V to ±18 V. |
| 14 | NC | unconnected | No internal connection. |
| 15 | RG2 | input | Gain-setting pin; for gains greater than 1, connect an external resistor between pins 2 and 15. |
| 16 | NC | unconnected | No internal connection. |

## CAD (KiCad official)

- Symbol: `INA217AIDWR`
- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`
- 3D model: SOIC-16-300mil (KiCad packages3D, STEP)
- 3D model files: `ina217aidwr-etched.step` / `ina217aidwr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ina217aidwr.step` / `ina217aidwr.glb` are the bare package body.
