RS621XF-Q1 from Jiangsu RUNIC Tech, in a SOT-23-5. 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 | OUT | output | Amplifier output with rail-to-rail swing; output signals that swing more than 0.5 V beyond the supply rails should be current-limited to ±10 mA or less. |
| 2 | V- | power_in | Negative (lowest) power supply; operates from single or dual supplies with VS = (V+) - (V-) between 2.5 V and 5.5 V, and VS must not exceed the 7 V absolute maximum. |
| 3 | +IN | input | Positive (noninverting) input; with VS = 5.5 V the common-mode input range is -0.1 V to +5.6 V, and inputs more than 0.5 V beyond the supply rails should be current-limited to 10 mA or less. |
| 4 | -IN | input | Negative (inverting) input; it shares the same input limits as the noninverting input, with inputs clamped to the supply rails and current-limited to 10 mA or less when driven more than 0.5 V beyond them. |
| 5 | V+ | power_in | Positive (highest) power supply; VS = (V+) - (V-) must be between 2.5 V and 5.5 V and must not exceed the 7 V absolute maximum. |
