TSV911AIYDT from UMW, 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; do not use as a routing node.
2	IN-	input	Inverting input of the op-amp. Rail-to-rail input; common-mode range (VCC-)-0.1 V to (VCC+)+0.1 V. Input bias current typ. 1 pA (max 10 pA @25 °C).
3	IN+	input	Non-inverting input of the op-amp. Rail-to-rail input; common-mode range (VCC-)-0.1 V to (VCC+)+0.1 V. Input bias current typ. 1 pA (max 10 pA @25 °C).
4	VCC-	power_in	Negative supply rail (or ground for single-supply operation). Supply range 2.5 V to 5.5 V referenced between VCC+ and VCC-; absolute max Vcc = 6 V.
5	NC	unconnected	No internal connection. Leave floating or tie to ground; do not use as a routing node.
6	OUT	output	Rail-to-rail op-amp output. High output current capability (35 mA typ source, 32 mA typ sink at Vo=2.5 V). VOH within ~15 mV of VCC+ with 10 kΩ load.
7	VCC+	power_in	Positive supply rail. Operating range 2.5 V to 5.5 V (2.3 V min for 0-125 °C), absolute max 6 V. Bypass with a 100 nF ceramic capacitor close to the pin.
8	NC	unconnected	No internal connection. Leave floating or tie to ground; do not use as a routing node.
