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. |
