**Jiangsu RUNIC Tech** · Operational Amplifier · SOT23-5

RS8411BPXF from Jiangsu RUNIC Tech, in a SOT23-5. 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 | +IN | input | Positive (noninverting) input; the common-mode input range runs from 100mV below V- to 2V below V+ at VS=±18V. |
| 2 | V- | power_in | Negative (lowest) power supply or ground, used for single-supply operation; supply range is 3V to 36V single-supply or ±1.5V to ±18V dual-supply. |
| 3 | -IN | input | Negative (inverting) input; input signals more than 0.2V beyond the supply rails should be current-limited to 10mA or less. |
| 4 | OUT | output | Output, rail-to-rail; output signals more than 0.2V beyond the supply rails should be current-limited to ±100mA or less. |
| 5 | V+ | power_in | Positive (highest) power supply; the supply voltage is (V+) - (V-), with an absolute maximum of 36V. |
