# LMV358MM

**HGSEMI** · Operational Amplifier · MSOP-8

LMV358MM from HGSEMI, 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 amplifier A, rail-to-rail output swing. |
| 2 | -INA | input | Inverting input of amplifier A, rail-to-rail input range extending 100 mV beyond the supply rails. |
| 3 | +INA | input | Non-inverting input of amplifier A, rail-to-rail input range extending 100 mV beyond the supply rails. |
| 4 | -Vs | power_in | Negative supply (ground in single-supply use); supply voltage VS+ to VS- operates from 1.8 V to 5.5 V and must not exceed 10 V absolute maximum. |
| 5 | +INB | input | Non-inverting input of amplifier B, rail-to-rail input range extending 100 mV beyond the supply rails. |
| 6 | -INB | input | Inverting input of amplifier B, rail-to-rail input range extending 100 mV beyond the supply rails. |
| 7 | OUTB | output | Output of amplifier B, rail-to-rail output swing. |
| 8 | +Vs | power_in | Positive supply; operates from 1.8 V to 5.5 V with 10 V absolute maximum between VS+ and VS-. |

## CAD (KiCad official)

- Symbol: `LMV358MM`
- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`
- 3D model: MSOP-8 (KiCad packages3D, STEP)
- 3D model files: `lmv358mm-etched.step` / `lmv358mm-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lmv358mm.step` / `lmv358mm.glb` are the bare package body.
