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 | +IN | input | Non-inverting analog input to the op-amp. Rail-to-rail common-mode range extending from V- - 0.1V to V+ + 0.1V; input bias current typically 10pA. Protected by ESD diodes to each supply; limit input current to <10mA if driven beyond the rails. |+| 2 | -VS | power_in | Negative supply rail (V-). Typically tied to ground in single-supply operation, or to the negative rail for split-supply operation. Total supply voltage (V+ to V-) must not exceed 6.6V absolute maximum; recommended range 2.1V to 6.0V. |+| 3 | -IN | input | Inverting analog input to the op-amp. Rail-to-rail common-mode range extending from V- - 0.1V to V+ + 0.1V; input bias current typically 10pA. Protected by ESD diodes to each supply; limit input current to <10mA if driven beyond the rails. |+| 4 | OUT | output | Rail-to-rail amplifier output. Output swings to within about 5mV of either supply rail into a 100kΩ load; short-circuit current ±40mA (sink or source). Indefinite short-circuit duration provided junction temperature is kept below 150°C. |+| 5 | +VS | power_in | Positive supply rail (V+). Operating supply range 2.1V to 6.0V (6.6V absolute max V+ to V-). Bypass locally with a low-ESR ceramic capacitor to -VS for best PSRR (typ. 90dB). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `TP321-TR`+- `TP321-TRTP321`+- `TP321-TRTP358`++## CAD (KiCad official)++- Symbol: `TP321-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:** [UMW datasheet](docs/tp321-tr-datasheet.pdf) (12 pp, sha256 `68ddde9e9628d435`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
