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

RS6332PXK 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 | OUT A | output | Output of amplifier A, which swings rail-to-rail and has a rated output current source of 120 mA at 25°C. |
| 2 | -IN A | input | Inverting input of amplifier A; input terminals are diode-clamped to the supply rails, and input signals beyond the rails by more than 0.5 V should be limited to 10 mA. |
| 3 | +IN A | input | Non-inverting input of amplifier A; the common-mode voltage range is -0.1 V to 5.6 V with Vs = 5.5 V. |
| 4 | V- | power_in | Negative supply rail; the part operates from a single supply of 2.1 V to 5.5 V or dual supplies of ±1.05 V to ±2.75 V. |
| 5 | +IN B | input | Non-inverting input of amplifier B; the common-mode voltage range is -0.1 V to 5.6 V with Vs = 5.5 V. |
| 6 | -IN B | input | Inverting input of amplifier B; input terminals are diode-clamped to the supply rails, and input signals beyond the rails by more than 0.5 V should be limited to 10 mA. |
| 7 | OUT B | output | Output of amplifier B, which swings rail-to-rail and has a rated output current source of 120 mA at 25°C. |
| 8 | V+ | power_in | Positive supply rail; supply voltage V+ to V- must not exceed the 7.0 V absolute maximum, and a 0.1 µF capacitor should be placed close across the supply pins. |
