OPA188AIDBVR from Texas Instruments, in a SOT-23-5. 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 ~15 mV of the supply rails; short-circuit current limited internally.
2	V-	power_in	Negative (lowest) power supply. Can be tied to GND for single-supply operation (4 V to 36 V total) or to a negative rail for split-supply operation (±2 V to ±18 V).
3	+IN	input	Noninverting input. Common-mode range includes the negative rail. Input terminals are diode-clamped to the supply rails; limit input current to 10 mA if signals exceed rails by more than 0.5 V.
4	-IN	input	Inverting input. Common-mode range includes the negative rail. Input terminals are diode-clamped to the supply rails; limit input current to 10 mA if signals exceed rails by more than 0.5 V.
5	V+	power_in	Positive (highest) power supply. Total supply span 4 V to 36 V (single) or ±2 V to ±18 V (split). Bypass close to the pin per layout guidelines.
