RS621PXF

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

RS621PXF 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 Amplifier output. Rail-to-rail output swing (within ~40 mV of rails with RL=2 kΩ, ~7 mV with RL=10 kΩ). Short-circuit current typically 50 mA.
2 V- power_in Negative supply rail. Tie to GND for single-supply operation or to the negative rail for dual-supply operation. Total supply (V+ to V-) must be 2.5 V to 5.5 V (7.0 V absolute max).
3 +IN input Non-inverting input. Rail-to-rail common-mode range from -0.1 V to +5.6 V with Vs=5.5 V. Input bias current typically 1 pA (10 pA max at 25°C).
4 -IN input Inverting input. Rail-to-rail common-mode range from -0.1 V to +5.6 V with Vs=5.5 V. Input bias current typically 1 pA (10 pA max at 25°C). Input terminals are diode-clamped to the supplies; limit fault current to ≤10 mA.
5 V+ power_in Positive supply rail. Operating range 2.5 V to 5.5 V referenced to V- (7.0 V absolute max). Decouple with a 0.1 uF capacitor placed close to the pin.
