Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | RG | passive | Gain-setting resistor terminal 1. Connect an external resistor RG between pins 1 and 8 to set gain: G = 1 + (100kΩ / RG). Leave open for unity gain. |+| 2 | VIN- | input | Inverting analog input. Input voltage range extends from (V-)+0.1V to (V+)-0.1V; input bias current typ ±70pA, max ±200pA. Includes internal RFI-filtered input network. |+| 3 | VIN+ | input | Non-inverting analog input. Input voltage range extends from (V-)+0.1V to (V+)-0.1V; input bias current typ ±70pA, max ±200pA. Includes internal RFI-filtered input network. |+| 4 | V- | power_in | Negative power supply. Single-supply range 1.8V to 5.5V referenced to V+; dual-supply range ±0.9V to ±2.75V. Absolute max supply (V+ − V−) = 7V. |+| 5 | REF | input | Reference input; sets the output offset (VOUT is referenced to this pin). Voltage range V- to V+; input resistance RIN ≈ 300kΩ. Drive from a low-impedance source to preserve CMRR. |+| 6 | VOUT | output | Amplifier output. Rail-to-rail: swings within ~50mV of the supply rails at RL=10kΩ. Short-circuit current −40/+5mA (continuous to common). Drives capacitive loads up to 500pF. |+| 7 | V+ | power_in | Positive power supply. Single-supply range 1.8V to 5.5V; dual-supply range ±0.9V to ±2.75V. Quiescent current typ 50µA (max 80µA). Bypass with 0.1µF close to the pin. |+| 8 | RG | passive | Gain-setting resistor terminal 2. Connect an external resistor RG between pins 1 and 8 to set gain: G = 1 + (100kΩ / RG). Leave open for unity gain. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | MSOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `INA333AIDGKRIDGKR`+- `INA333AIDGKRIDGKT`+- `INA333AIDGKRIDRGR`+- `INA333AIDGKRIDRGT`++## CAD (KiCad official)++- Symbol: `INA333AIDGKR`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/ina333ai.pdf) (23 pp, sha256 `9d5c1a1939a60413`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
