RS722PXK-Q1

Jiangsu RUNIC Tech · Operational Amplifier · SOIC-8

RS722PXK-Q1 from Jiangsu RUNIC Tech, in a SOIC-8. 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 OUTA output Channel A output; the pin voltage is absolute-maximum rated to (V-)-0.5 V to (V+)+0.5 V, and the output is continuously short-circuit protected to ground per the Absolute Maximum Ratings note.
2 -INA input Channel A inverting input; the signal input is absolute-maximum rated to (V-)-0.5 V to (V+)+0.5 V, and inputs that swing more than 0.5 V beyond the supply rails should be current-limited to 10 mA or less.
3 +INA input Channel A noninverting input; the common-mode voltage range is -0.1 V to 5.6 V with VS = 5.5 V, and the signal input is absolute-maximum rated to (V-)-0.5 V to (V+)+0.5 V.
4 V- power_in Negative (lowest) power supply; the supply is 2.7 V to 5.5 V single-supply (or ±1.35 V to ±2.75 V dual) and must not exceed 7 V absolute maximum.
5 +INB input Channel B noninverting input; the common-mode voltage range is -0.1 V to 5.6 V with VS = 5.5 V, and the signal input is absolute-maximum rated to (V-)-0.5 V to (V+)+0.5 V.
6 -INB input Channel B inverting input; the signal input is absolute-maximum rated to (V-)-0.5 V to (V+)+0.5 V, and inputs that swing more than 0.5 V beyond the supply rails should be current-limited to 10 mA or less.
7 OUTB output Channel B output; the pin voltage is absolute-maximum rated to (V-)-0.5 V to (V+)+0.5 V, and the output is continuously short-circuit protected to ground per the Absolute Maximum Ratings note.
8 V+ power_in Positive (highest) power supply; the supply is 2.7 V to 5.5 V single-supply (or ±1.35 V to ±2.75 V dual) and must not exceed 7 V absolute maximum.
