RS8551XF-Q1

Jiangsu RUNIC Tech · Precision Op Amps · SOT-23-5

RS8551XF-Q1 from Jiangsu RUNIC Tech, 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; the datasheet specifies a rail-to-rail output swing, with VOH/VOL typically 8 mV and at most 20 mV from the rails at 25°C with RL = 10 kΩ.
2	V-	power_in	Negative (lowest) power supply; the device operates with a supply of +2.7 V to +5.5 V single-supply (±1.35 V to ±2.75 V dual-supply).
3	+IN	input	Positive (noninverting) input; the common-mode voltage range extends from (V-) - 0.1 V to (V+) + 0.1 V.
4	-IN	input	Negative (inverting) input; the common-mode voltage range extends from (V-) - 0.1 V to (V+) + 0.1 V.
5	V+	power_in	Positive (highest) power supply; supply voltage must not exceed the 7 V absolute maximum.
