Gainsil · Precision Op Amps · SOT-23-5

GS6551-TR from Gainsil, 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 with rail-to-rail swing, able to deliver 65mA output current (60mA short-circuit limit) per the electrical characteristics.
2	VSS	power_in	Negative supply (ground in single-supply operation); input common-mode range extends to VSS-0.1V and supply range VDD to VSS is 1.8V to 5.5V.
3	IN+	input	Non-inverting input, rail-to-rail with a common-mode range of VSS-0.1V to VDD+0.1V and an absolute maximum of VSS-0.5V to VDD+0.5V.
4	IN-	input	Inverting input, rail-to-rail with a common-mode range of VSS-0.1V to VDD+0.1V and an absolute maximum of VSS-0.5V to VDD+0.5V.
5	VDD	power_in	Positive supply, 1.8V to 5.5V single supply (7.5V absolute maximum VDD to VSS), bypassed with a 0.1µF ceramic capacitor placed close to the pin.
