M2125G-AF5-R

UTC Unisonic Tech · Operational Amplifier · SOT-25

M2125G-AF5-R from UTC Unisonic Tech, in a SOT-25. 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 IN+ input Non-inverting input (+INPUT) of the operational amplifier. Common-mode input range 0 V to 3.5 V at V+=5 V.
2 GND power_in Ground / negative supply reference for the op-amp.
3 IN- input Inverting input (-INPUT) of the operational amplifier.
4 OUT output Op-amp output. Maximum output voltage swing typ. 3.5 V with RL=2 kΩ at V+=5 V; source current typ. 30 mA, sink current typ. 20 mA.
5 V+ power_in Positive supply pin. Operating range ±2.7 V to 20 V (single-supply up to +20 V). Typical operating current 1.0 mA.
