# LMV358ARZ

**HTCSEMI** · Operational Amplifier · SOP-8

LMV358ARZ from HTCSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Amplifier A output. Rail-to-rail output; voltage range extends to within ~10mV of each supply rail. Drives up to 50mA typ. |
| 2 | INNA | input | Inverting input of amplifier A. Input voltage range 0 to VDD-0.1V (beyond-the-rails capable). |
| 3 | INPA | input | Non-inverting input of amplifier A. Voltage range 0 to VDD-0.1V. |
| 4 | GND | power_in | Ground / negative supply. Connect to the most negative supply rail. |
| 5 | INPB | input | Non-inverting input of amplifier B. Voltage range 0 to VDD-0.1V. |
| 6 | INNB | input | Inverting input of amplifier B. Voltage range 0 to VDD-0.1V. |
| 7 | OUTB | output | Amplifier B output. Rail-to-rail output; swings to within ~10mV of each rail. Output current up to 50mA typ. |
| 8 | VDD | power_in | Positive supply. Operating range 2.5V to 5.5V, absolute maximum 6V. Bypass with a local ceramic capacitor to GND. |

## CAD (KiCad official)

- Symbol: `LMV358ARZ`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `lmv358arz-etched.step` / `lmv358arz-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lmv358arz.step` / `lmv358arz.glb` are the bare package body.
