RS358AXM from Jiangsu RUNIC Tech, in a MSOP-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 | Output of amplifier A. Rail-to-rail output; typical output swing to within 8 mV of the rails with RL = 10 kΩ, source current capability ~130 mA. |
| 2 | -INA | input | Inverting input of amplifier A. Rail-to-rail input range −0.1 V to +5.6 V with Vs = 5.5 V; typical input bias current 10 pA. |
| 3 | +INA | input | Non-inverting input of amplifier A. Rail-to-rail input range −0.1 V to +5.6 V with Vs = 5.5 V; input terminals are diode-clamped to the supply rails, currents must be limited to ±10 mA if signals exceed rails by >0.5 V. |
| 4 | V- | power_in | Negative supply rail (or GND in single-supply operation). Total supply (V+) − (V−) must be between 2.5 V and 5.5 V; absolute maximum V+ to V− is 7.0 V. |
| 5 | +INB | input | Non-inverting input of amplifier B. Rail-to-rail input range −0.1 V to +5.6 V with Vs = 5.5 V; input terminals are diode-clamped to the supply rails. |
| 6 | -INB | input | Inverting input of amplifier B. Rail-to-rail input range −0.1 V to +5.6 V with Vs = 5.5 V; typical input bias current 10 pA. |
| 7 | OUTB | output | Output of amplifier B. Rail-to-rail output; typical output swing to within 8 mV of the rails with RL = 10 kΩ, source current capability ~130 mA. |
| 8 | V+ | power_in | Positive supply rail. Operating supply 2.5 V to 5.5 V (single-supply) or ±1.25 V to ±2.75 V (dual-supply). Place a 0.1 µF decoupling capacitor closely across the supply pins. |
