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

RS6332PXM from Jiangsu RUNIC Tech, in a MSOP-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 datasheet gives the output current source rating of 120 mA and the absolute maximum signal output current of ±140 mA. |
| 2 | -INA | input | Inverting input of channel A, which must stay within the input voltage range of (V-)-0.5 V to (V+)+0.5 V and be current-limited to 10 mA if it can swing more than 0.5 V beyond the supply rails. |
| 3 | +INA | input | Noninverting input of channel A, which has a common-mode voltage range of -0.1 V to 5.6 V at Vs = 5.5 V and must stay within (V-)-0.5 V to (V+)+0.5 V. |
| 4 | V- | power_in | Negative (lowest) power supply pin; single-supply operation uses 2.1 V to 5.5 V between V+ and V-, or dual supplies of ±1.05 V to ±2.75 V. |
| 5 | +INB | input | Noninverting input of channel B, which has a common-mode voltage range of -0.1 V to 5.6 V at Vs = 5.5 V and must stay within (V-)-0.5 V to (V+)+0.5 V. |
| 6 | -INB | input | Inverting input of channel B, which must stay within the input voltage range of (V-)-0.5 V to (V+)+0.5 V and be current-limited to 10 mA if it can swing more than 0.5 V beyond the supply rails. |
| 7 | OUTB | output | Output of channel B; the datasheet gives the output current source rating of 120 mA and the absolute maximum signal output current of ±140 mA. |
| 8 | V+ | power_in | Positive (highest) power supply pin; the absolute maximum supply voltage Vs = (V+) - (V-) is 7 V and the recommended range is 2.1 V to 5.5 V. |
