RS521XF

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

RS521XF from Jiangsu RUNIC Tech, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT output Amplifier output with rail-to-rail swing (within 7mV of the rail at RL=10kΩ) and short-circuit current of 80mA typical.
2 V- power_in Negative supply or ground; total supply V+ to V- is 2.5V to 5.5V, with 7.0V absolute maximum.
3 +IN input Non-inverting input with rail-to-rail common-mode range of -0.1V to 5.6V at Vs=5.5V, and input voltage limited to -0.5V to (V+)+0.5V.
4 -IN input Inverting input with rail-to-rail common-mode range of -0.1V to 5.6V at Vs=5.5V, and input voltage limited to -0.5V to (V+)+0.5V.
5 V+ power_in Positive supply, 2.5V to 5.5V relative to V- (7.0V absolute maximum), with a 0.1uF capacitor recommended close across the supply pins.

CAD (KiCad official)

  • Symbol: RS521XF
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: rs521xf-etched.step / rs521xf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rs521xf.step / rs521xf.glb are the bare package body.
