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 | OUT | output | Amplifier output. Rail-to-rail output stage; swings within ~10mV of the rails with light loads (>500kOhm) and delivers ~58mA source/sink at V_S=5V. |+| 2 | VSS | power_in | Negative supply / ground. For single-supply operation tie to GND; for dual-supply operation connect to the negative rail (±1.05V to ±2.75V). Bypass with 0.1uF ceramic to V_DD. |+| 3 | IN+ | input | Non-inverting input. Rail-to-rail common-mode range extends 100mV beyond each supply rail (V_SS-0.1V to V_DD+0.1V). Input bias current ~1pA typ. |+| 4 | IN- | input | Inverting input. Rail-to-rail common-mode range extends 100mV beyond each supply rail (V_SS-0.1V to V_DD+0.1V). Input bias current ~1pA typ. |+| 5 | VDD | power_in | Positive supply. Single-supply range 2.1V to 5.5V (absolute max 7.5V V_DD to V_SS). Bypass with a 0.1uF ceramic capacitor placed close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Gainsil |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `GS8521-TRTR`+- `GS8521-TRSR`+- `GS8521-TRMR`+- `GS8521-TRTR`+- `GS8521-TRSR`++## CAD (KiCad official)++- Symbol: `GS8521-TR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Gainsil datasheet](docs/gs8521-tr-datasheet.pdf) (13 pp, sha256 `20f611aa30eb6027`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
