OPA2378AIDCNT from Texas Instruments, in a SOT-23-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	Out A	output	Channel A rail-to-rail output, which swings within 10mV of the supplies.
2	-In A	input	Channel A inverting input; input common-mode range extends 0.05V beyond the supply rails, and input current must be limited to 10mA if signals swing more than 0.3V beyond the rails.
3	+In A	input	Channel A non-inverting input; input common-mode range extends 0.05V beyond the supply rails, and input current must be limited to 10mA if signals swing more than 0.3V beyond the rails.
4	V-	power_in	Negative supply (ground in single-supply use); total supply voltage VS = (V+) - (V-) is 2.2V to 5.5V, with an absolute maximum of 7V.
5	+In B	input	Channel B non-inverting input; input common-mode range extends 0.05V beyond the supply rails, and input current must be limited to 10mA if signals swing more than 0.3V beyond the rails.
6	-In B	input	Channel B inverting input; input common-mode range extends 0.05V beyond the supply rails, and input current must be limited to 10mA if signals swing more than 0.3V beyond the rails.
7	Out B	output	Channel B rail-to-rail output, which swings within 10mV of the supplies.
8	V+	power_in	Positive supply; total supply voltage VS = (V+) - (V-) is 2.2V to 5.5V, with an absolute maximum of 7V, and a 0.1µF capacitor should be placed closely across the supply pins.
