**MSKSEMI** · Operational Amplifier · SOP-8

LMV358-MS from MSKSEMI, in a SOP-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 | 1OUT | output | Output of amplifier 1, a rail-to-rail output that swings within 50 mV of the rails. |
| 2 | 1IN- | input | Inverting input of amplifier 1, with a common-mode voltage range of (V-)-0.1 V to (V+)+0.1 V. |
| 3 | 1IN+ | input | Noninverting input of amplifier 1, with a common-mode voltage range of (V-)-0.1 V to (V+)+0.1 V. |
| 4 | GND | power_in | Negative (lowest) power supply pin; the device is specified for a 2.1 V to 5.5 V supply (±1.35 V to ±2.75 V). |
| 5 | 2IN+ | input | Noninverting input of amplifier 2, with a common-mode voltage range of (V-)-0.1 V to (V+)+0.1 V. |
| 6 | 2IN- | input | Inverting input of amplifier 2, with a common-mode voltage range of (V-)-0.1 V to (V+)+0.1 V. |
| 7 | 2OUT | output | Output of amplifier 2, a rail-to-rail output that swings within 50 mV of the rails. |
| 8 | Vcc+ | power_in | Positive (highest) power supply pin; the device is specified for a 2.1 V to 5.5 V supply. |
