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 | OUT1 | output | Output of op-amp A. Class-A output at small signals, class-B at large signals, sourcing up to ~30 mA and sinking up to ~8 mA at V+=15 V. Short-circuit-to-ground current is ~30-85 mA at V+=15 V; sustained shorts to V+ will destroy the die. |+| 2 | IN1- | input | Inverting input of op-amp A. High-impedance PNP input with ~30 nA typical input bias current and ~3 mV typical input offset voltage. Absolute-max input voltage -0.3 V to 40 V; do not drive below V- - 0.3 V or the internal PNP base-collector diode will conduct. |+| 3 | IN1+ | input | Non-inverting input of op-amp A. Common-mode input range extends from ground (V-) up to V+ - 1.5 V, allowing single-supply operation. Same absolute-max limits as IN1-. |+| 4 | GND | power_in | Negative supply / ground (V-). In single-supply operation tie to 0 V; in split-supply operation tie to the negative rail. Total supply voltage (V+ - V-) must not exceed 40 V. |+| 5 | IN2+ | input | Non-inverting input of op-amp B. Same electrical characteristics as IN1+: rail-to-ground common-mode range up to V+ - 1.5 V and 30 nA typical bias current. |+| 6 | IN2- | input | Inverting input of op-amp B. Same electrical characteristics as IN1-: ~30 nA bias current, ~3 mV offset, and same absolute-max voltage limits. |+| 7 | OUT2 | output | Output of op-amp B. Same drive capability as OUT1: ~30 mA source / ~8 mA sink at V+=15 V, VO=2 V, with VOL ~5 mV at RL=10 k to ground. |+| 8 | VCC | power_in | Positive supply (V+). Operating range 2.5 V to 36 V single-supply (up to 40 V absolute max V+ - V-). Bypass with 0.1 uF ceramic to GND close to the pin to reduce noise coupling. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Hangzhou Ruimeng Tech |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `MS358MS321`+- `MS358`+- `MS358MS324`+- `MS358MS324N`++## CAD (KiCad official)++- Symbol: `MS358`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Hangzhou Ruimeng Tech datasheet](docs/ms358-datasheet.pdf) (None pp, sha256 `fdcf8a1a1925c383`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
