GTV321BS5 from GTIC, 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	+IN	input	Noninverting analog input. Rail-to-rail common-mode range from (V-) - 0.1 V to (V+) + 0.1 V (typ -0.1 V to +5.6 V at Vs=5.5 V). Input bias current ~30 pA typ; diode-clamped to supply rails (limit external swings beyond rails to <10 mA).
2	V-	power_in	Negative (lowest) supply rail, or ground for single-supply operation. Vs = (V+) - (V-) rated 2.5 V min to 5.5 V max (6.5 V absolute max).
3	-IN	input	Inverting analog input. Rail-to-rail common-mode range; ultra-low input bias current (~30 pA typ). Diode-clamped to supply rails.
4	OUT	output	Rail-to-rail amplifier output. Output swing to within ~5 mV (typ) / 15 mV (max) of either rail with RL=10 kΩ. Short-circuit / drive current ~70 mA typ.
5	V+	power_in	Positive (highest) supply rail. Recommended 2.5 V to 5.5 V single-supply relative to V- (absolute max 6.5 V). Place a 0.1 µF decoupling capacitor close to this pin.
