FP103DR-LF from Advanced Analog Technology, 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	VO1	output	OPA1 output. Op-amp output stage; can source up to 50mA typ and sink up to 10mA typ.
2	VI1	input	OPA1 inverting input. Internally tied to the 2.5V VREF reference feedback path in the block diagram (this op-amp is used with the on-chip 2.5V reference on its non-inverting side).
3	VNI1	input	OPA1 non-inverting input. Internally connected to the 2.5V precision VREF reference (per the functional block diagram).
4	VEE	power_in	IC ground or negative supply voltage. Negative supply rail for the amplifiers; typically tied to GND in single-supply operation.
5	VNI2	input	OPA2 non-inverting input. General-purpose op-amp input; common-mode range 0V to (Vcc+)-1.5V.
6	VI2	input	OPA2 inverting input. General-purpose op-amp input; typ input bias current 20nA.
7	VO2	output	OPA2 output. Op-amp output stage; can source up to 50mA typ and sink up to 10mA typ.
8	VCC	power_in	Positive supply voltage. Operating range 3V to 32V (or +/-16V split); absolute max 36V. Feeds both op-amps and the internal 2.5V reference regulator.
