OPA376M5 from HGSEMI, 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; can source/sink typ. 30mA, short-circuit limit 43mA into 10Ω.
2	VSS	power_in	Negative supply / ground. Single-supply operation from 1.8V to 5.5V referenced to VSS; VDD−VSS absolute max +7.5V.
3	IN+	input	Non-inverting analog input. Rail-to-rail input range VSS−0.5V to VDD+0.5V (abs max); 20pA typical input bias current.
4	IN-	input	Inverting analog input. Rail-to-rail input range VSS−0.5V to VDD+0.5V (abs max); 20pA typical input bias current.
5	VDD	power_in	Positive supply. 1.8V to 5.5V single-supply; absolute max VDD−VSS = 7.5V. Decouple with 100nF close to pin.
