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

RS358XM 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 | OUT A | output | Output of amplifier A, which swings rail-to-rail and has a short-circuit current of 54 mA (typ) at 25°C. |
| 2 | -IN A | input | Inverting input of amplifier A; the input common-mode range is -0.1 V to 5.6 V when Vs = 5.5 V. |
| 3 | +IN A | input | Non-inverting input of amplifier A; the input common-mode range is -0.1 V to 5.6 V when Vs = 5.5 V. |
| 4 | V- | power_in | Negative supply rail, with the operating supply range of 2.5 V to 5.5 V (V+ to V-) and an absolute maximum supply of 7.0 V. |
| 5 | +IN B | input | Non-inverting input of amplifier B; the input common-mode range is -0.1 V to 5.6 V when Vs = 5.5 V. |
| 6 | -IN B | input | Inverting input of amplifier B; the input common-mode range is -0.1 V to 5.6 V when Vs = 5.5 V. |
| 7 | OUT B | output | Output of amplifier B, which swings rail-to-rail and has a short-circuit current of 54 mA (typ) at 25°C. |
| 8 | V+ | power_in | Positive supply rail, with the operating supply range of 2.5 V to 5.5 V (V+ to V-) and an absolute maximum supply of 7.0 V. |
