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.
