SGMICRO · Operational Amplifier · SOT-23-5

SGM8521XN5 from SGMICRO, 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 swing; typical VOH = 4.997V and VOL = 0.005V at VS = 5V with RL = 500kΩ. Source/sink current typically 87mA/76mA into 10Ω.
2 -VS power_in Negative supply rail (typically GND for single-supply operation). Supply voltage range from -VS to +VS is 2.1V to 5.5V, absolute max 6V.
3 +IN input Non-inverting op-amp input. Rail-to-rail input common-mode range; input voltage range -0.1V to 5.6V with VS = 5.5V. Typical input bias current 3pA.
4 -IN input Inverting op-amp input. Rail-to-rail input common-mode range; input voltage range -0.1V to 5.6V with VS = 5.5V. Typical input bias current 3pA.
5 +VS power_in Positive supply rail. Operating supply voltage 2.1V to 5.5V (absolute max 6V from +VS to -VS). Quiescent current 5.5µA typical.
