# LM358A-VR

**3PEAK** · Operational Amplifier · MSOP-8

LM358A-VR from 3PEAK, 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, with rail-to-rail output swing. |
| 2 | -IN A | input | Inverting input of amplifier A; input voltage range is (-VS) - 0.3V to (+VS) + 0.3V and input current should be limited to ±10mA. |
| 3 | +IN A | input | Non-inverting input of amplifier A; common-mode range extends from V- to (V+) - 1.5V at 25°C. |
| 4 | -VS | power_in | Negative supply (ground in single-supply use); total supply (+VS)-(-VS) is 3V to 36V, absolute maximum 40V. |
| 5 | +IN B | input | Non-inverting input of amplifier B; common-mode range extends from V- to (V+) - 1.5V at 25°C. |
| 6 | -IN B | input | Inverting input of amplifier B; input voltage range is (-VS) - 0.3V to (+VS) + 0.3V and input current should be limited to ±10mA. |
| 7 | OUT B | output | Output of amplifier B, with rail-to-rail output swing. |
| 8 | +VS | power_in | Positive supply; total supply (+VS)-(-VS) is 3V to 36V, absolute maximum 40V. |
