GT8551S5

GTIC · Precision OpAmps · SOT-23-5

GT8551S5 from GTIC, in a SOT-23-5. 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	output	Amplifier output, rail-to-rail swing.
2	V-	power_in	Negative (lowest) power supply; single supply 1.8 V to 5.5 V across V+ and V-.
3	+IN	input	Positive (noninverting) input, rail-to-rail, input range (V-)-0.1 V to (V+)+0.1 V.
4	-IN	input	Negative (inverting) input, rail-to-rail, input range (V-)-0.1 V to (V+)+0.1 V.
5	V+	power_in	Positive (highest) power supply; absolute maximum supply voltage 6.5 V, with a 0.1 µF capacitor placed closely across the supply pins.
