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 pin. Connect an external gain resistor between pin 1 and pin 8 to set gain: G = 1 + (49.4kΩ/RG). Gain range 1 to 10000. |+| 2 | IN- | input | Inverting input pin of the instrumentation amplifier. Input impedance 10GΩ || 4pF. Input bias current 15nA typical. |+| 3 | IN+ | input | Non-inverting input pin of the instrumentation amplifier. Input impedance 10GΩ || 4pF. Input bias current 15nA typical. |+| 4 | -VS | power_in | Negative power supply pin. Operating range -2.3V to -18V for dual supply, or GND for single-supply operation up to 36V total across +VS to -VS. |+| 5 | REF | input | Voltage reference pin used to shift the output level. Must be driven from a low-impedance source (reference input resistance ~18kΩ, reference input current ~30µA typ). |+| 6 | OUT | output | Rail-to-rail output pin. Drives load (RL = 2kΩ nominal). Short-circuit current typically 24mA. Output swing within ~310mV/150mV of the supply rails at ±18V. |+| 7 | +VS | power_in | Positive power supply pin. Operating range +2.3V to +18V for dual supply, or 4.6V to 36V for single-supply operation. |+| 8 | RG | passive | Gain setting pin. Connect an external gain resistor between pin 1 and pin 8 to set gain: G = 1 + (49.4kΩ/RG). Gain range 1 to 10000. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | SGMICRO |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `SGM620XS8G/TR`++## CAD (KiCad official)++- Symbol: `SGM620XS8G`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [SGMICRO datasheet](docs/sgm620xs8g-datasheet.pdf) (19 pp, sha256 `8da76555e7fcc99b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
