SGM721XN5

SGMICRO · Operational Amplifier · SOT-23-5

SGM721XN5 from SGMICRO, 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, which swings rail-to-rail with heavy loads (0.076 V typ from the rail at RL = 600 Ω, 5 V supply).
2 -VS power_in Negative supply rail; the part operates from 2.1 V to 5.5 V single supply, with absolute maximum supply of 7 V and input common-mode limits of (-VS) - 0.3 V to (+VS) + 0.3 V.
3 +IN input Non-inverting input with rail-to-rail common-mode range of -0.1 V to 5.6 V at VS = 5.5 V, and absolute limits of (-VS) - 0.3 V to (+VS) + 0.3 V.
4 -IN input Inverting input with the same common-mode range as +IN, -0.1 V to 5.6 V at VS = 5.5 V, and absolute limits of (-VS) - 0.3 V to (+VS) + 0.3 V.
5 +VS power_in Positive supply rail; the part operates from 2.1 V to 5.5 V, with absolute maximum supply of 7 V (+VS to -VS).

CAD (KiCad official)

  • Symbol: SGM721XN5
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: sgm721xn5-etched.step / sgm721xn5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sgm721xn5.step / sgm721xn5.glb are the bare package body.
