RS8031XF

Jiangsu RUNIC Tech · Operational Amplifier · SOT-23-5

RS8031XF from Jiangsu RUNIC Tech, in a SOT-23-5. 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 OUT output Op-amp output. Rail-to-rail output, typical output swing within 5 mV of the rails with RL = 50 kΩ; short-circuit output current typically 11 mA.
2 V- power_in Negative supply rail (or GND in single-supply operation). Total supply V+ to V- must be within 1.4 V to 5.5 V (absolute max 7.0 V).
3 +IN input Non-inverting input. Rail-to-rail common-mode range from -0.1 V to +5.6 V at Vs = 5.5 V; input bias current typically 1 pA. Diode-clamped to supply rails; limit input current to 10 mA when signal exceeds rails by >0.5 V.
4 -IN input Inverting input. Rail-to-rail common-mode range from -0.1 V to +5.6 V at Vs = 5.5 V; input bias current typically 1 pA. Diode-clamped to supply rails.
5 V+ power_in Positive supply rail. Operating range 1.4 V to 5.5 V (absolute max 7.0 V between V+ and V-). Quiescent current typically 750 nA per amplifier.
