**Jiangsu RUNIC Tech** · Operational Amplifier · SOIC-8

RS8462PXK from Jiangsu RUNIC Tech, in a SOIC-8. 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 | OUTA | output | Output of channel A; the absolute maximum ratings list the output short-circuit condition as continuous (short to ground, one amplifier per package). |
| 2 | -INA | input | Inverting input of channel A; signal input pins are diode-clamped to the supply rails, and inputs that swing more than 0.5V beyond the rails should be current-limited to 10mA or less. |
| 3 | +INA | input | Noninverting input of channel A; signal input pins are diode-clamped to the supply rails, and inputs that swing more than 0.5V beyond the rails should be current-limited to 10mA or less. |
| 4 | V- | power_in | Negative (lowest) power supply or ground for single-supply operation; the recommended supply is 4.5V to 32V single-supply or ±2.25V to ±16V dual-supply. |
| 5 | +INB | input | Noninverting input of channel B; signal input pins are diode-clamped to the supply rails, and inputs that swing more than 0.5V beyond the rails should be current-limited to 10mA or less. |
| 6 | -INB | input | Inverting input of channel B; signal input pins are diode-clamped to the supply rails, and inputs that swing more than 0.5V beyond the rails should be current-limited to 10mA or less. |
| 7 | OUTB | output | Output of channel B; the absolute maximum ratings list the output short-circuit condition as continuous (short to ground, one amplifier per package). |
| 8 | V+ | power_in | Positive (highest) power supply; absolute maximum supply voltage (V+)-(V-) is 36V. |
