RS358AXM

Jiangsu RUNIC Tech · Operational Amplifier · MSOP-8

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.
