RS8511XF

Jiangsu RUNIC Tech · Precision OpAmps · SOT23-5

RS8511XF from Jiangsu RUNIC Tech, in a SOT23-5. 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, diode-clamped to the supply rails with signals beyond 0.5V outside the rails current-limited to ±55mA or less.
2 V- power_in Negative (lowest) power supply; supply range Vs is 2.3V to 5.5V single-supply (±1.15V to ±2.75V dual).
3 +IN input Positive (noninverting) input, diode-clamped to the supply rails with input current limited to 10mA or less beyond 0.5V outside rails.
4 -IN input Negative (inverting) input, diode-clamped to the supply rails with input current limited to 10mA or less beyond 0.5V outside rails.
5 V+ power_in Positive (highest) power supply; absolute maximum supply 7V, with a 0.1uF capacitor recommended across the supply pins.
