Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Output of amplifier channel A. Rail-to-rail output; can source/sink up to ~140 mA typical, short-circuit protected. |
| 2 | -INA | input | Inverting input, channel A. Rail-to-rail CMOS input; common-mode range -0.2V to +5.7V with Vs=5.5V. Input bias current ~1 pA typical. |
| 3 | +INA | input | Noninverting input, channel A. Rail-to-rail CMOS input; common-mode range -0.2V to +5.7V with Vs=5.5V. Input bias current ~1 pA typical. |
| 4 | V- | power_in | Negative (lowest) power supply. Connect to ground for single-supply operation; supports single-supply 2.5V to 5.5V or dual-supply ±1.25V to ±2.75V. |
| 5 | +INB | input | Noninverting input, channel B. Rail-to-rail CMOS input; common-mode range -0.2V to +5.7V with Vs=5.5V. Input bias current ~1 pA typical. |
| 6 | -INB | input | Inverting input, channel B. Rail-to-rail CMOS input; common-mode range -0.2V to +5.7V with Vs=5.5V. Input bias current ~1 pA typical. |
| 7 | OUTB | output | Output of amplifier channel B. Rail-to-rail output; can source/sink up to ~140 mA typical, short-circuit protected. |
| 8 | V+ | power_in | Positive (highest) power supply. Single-supply 2.5V to 5.5V, absolute max Vs=(V+)-(V-)=7V. Quiescent current ~1.1 mA per amplifier. |

3D model downloads
Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
rs722pxk.step |
122 KB | You want the bare part, or you mark your own boards. |
rs722pxk-etched.step |
1.7 MB | You want the part with RS722PXK already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 437 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
