**Jiangsu RUNIC Tech** · Operational Amplifier · SOT-23-5

RS8461PXF 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; the datasheet lists continuous output short-circuit as an absolute maximum rating (short to ground, one amplifier per package). |
| 2 | V- | power_in | Negative (lowest) power supply; supply voltage VS = (V+) - (V-) is 4.5 V to 32 V single-supply or ±2.25 V to ±16 V dual-supply, with 36 V absolute maximum. |
| 3 | +IN | input | Positive (noninverting) input; signal input pins are diode-clamped to the supply rails, with input voltage limited to (V-)-0.5 V to (V+)+0.5 V and input current limited to ±10 mA. |
| 4 | -IN | input | Negative (inverting) input; signal input pins are diode-clamped to the supply rails, with input voltage limited to (V-)-0.5 V to (V+)+0.5 V and input current limited to ±10 mA. |
| 5 | V+ | power_in | Positive (highest) power supply; supply voltage VS = (V+) - (V-) is 4.5 V to 32 V single-supply or ±2.25 V to ±16 V dual-supply, with 36 V absolute maximum. |
