GS8141-TR

Gainsil · Operational Amplifier · SOT-23-5

GS8141-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, sourcing and sinking 20mA (typ) into a 10Ω load.
2	VSS	power_in	Negative supply or ground; the supply range VDD to VSS is 1.4V to 5.5V (absolute maximum 7.5V).
3	IN+	input	Non-inverting input with rail-to-rail common-mode range of VSS-0.1V to VDD+0.1V, limited to VSS-0.5V to VDD+0.5V absolute maximum.
4	IN-	input	Inverting input with rail-to-rail common-mode range of VSS-0.1V to VDD+0.1V, limited to VSS-0.5V to VDD+0.5V absolute maximum.
5	VDD	power_in	Positive supply, 1.4V to 5.5V single supply, with a 0.1µF ceramic bypass capacitor placed close to the pin.
