# INA826AIDGK

**Texas Instruments** · Instrumentation Amplifiers · MSOP-8

INA826AIDGK from Texas Instruments, in a MSOP-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 | -IN | input | Negative (inverting) input of the instrumentation amplifier. |
| 2 | RG | passive | Gain setting pin; place a gain resistor between pin 2 and pin 3. |
| 3 | RG | passive | Gain setting pin; place a gain resistor between pin 2 and pin 3. |
| 4 | +IN | input | Positive (noninverting) input of the instrumentation amplifier. |
| 5 | -VS | power_in | Negative supply. |
| 6 | REF | input | Reference input; this pin must be driven by low impedance. |
| 7 | VOUT | output | Amplifier output. |
| 8 | +VS | power_in | Positive supply. |

## CAD (KiCad official)

- Symbol: `INA826AIDGK`
- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`
- 3D model: MSOP-8 (KiCad packages3D, STEP)
- 3D model files: `ina826aidgk-etched.step` / `ina826aidgk-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ina826aidgk.step` / `ina826aidgk.glb` are the bare package body.
