NCS325SN2T1G from onsemi, in a TSOP-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 to within ~12 mV of VDD and ~8 mV of VSS at no load. Short-circuit current typ +/-5 mA; continuous short-circuit protected.
2	VSS	power_in	Negative supply / ground rail. Supply voltage VDD-VSS ranges 1.8 V to 5.5 V (abs max 6 V).
3	IN+	input	Non-inverting input. Input common-mode range VSS-0.1 V to VDD+0.1 V (rail-to-rail). Input bias current typ +/-50 pA; input resistance 15 GOhm typ.
4	IN-	input	Inverting input. Input common-mode range VSS-0.1 V to VDD+0.1 V (rail-to-rail). Input bias current typ +/-50 pA; input offset current typ +/-100 pA.
5	VDD	power_in	Positive supply rail. 1.8 V to 5.5 V operating (6 V abs max). Quiescent current typ 21 uA, max 35 uA at 25 degC.
