HGV8541M from HGSEMI, in a SOP-8. 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	NC	unconnected	No internal connection. Leave floating or tie to ground for best PCB practice.
2	-IN	input	Inverting input of the operational amplifier. Rail-to-rail input range from GND (0 V) to VS (up to 5.5 V). Very low input bias current (4 pA typ) enables high-impedance source usage.
3	+IN	input	Non-inverting input of the operational amplifier. Rail-to-rail common-mode range from GND (0 V) to VS. Very low input bias current (4 pA typ).
4	V-	power_in	Negative supply / ground pin. Tie to GND in single-supply operation, or to the negative rail in split-supply operation. Total supply span (V+ minus V-) must not exceed 6 V absolute maximum.
5	NC	unconnected	No internal connection. Leave floating or tie to ground for best PCB practice.
6	OUT	output	Rail-to-rail amplifier output. Drives up to ~15 mA (VOUT = VS - 1 V) with short-circuit current ±20 mA. Closed-loop output impedance ~50 Ω at 200 kHz, AV=1.
7	V+	power_in	Positive supply pin. Single-supply operation from 2.7 V to 5.5 V (absolute maximum 6 V). Supply current is only 45 uA typical per amplifier. Decouple with a local 0.1 uF ceramic capacitor to V-.
8	NC	unconnected	No internal connection. Leave floating or tie to ground for best PCB practice.
