RS6331PXF 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, which swings rail-to-rail; output signals that exceed the supply rails by more than 0.5 V should be current-limited to ±140 mA or less. |
| 2 | V- | power_in | Negative (lowest) power supply; the supply Vs=(V+)-(V-) is 2.1 V to 5.5 V recommended with a 7 V absolute maximum. |
| 3 | +IN | input | Positive (noninverting) input with a common-mode range of -0.1 V to 5.6 V at Vs=5.5 V; input signals that exceed the supply rails by more than 0.5 V should be current-limited to 10 mA or less. |
| 4 | -IN | input | Negative (inverting) input with the same limits as the noninverting input; input signals that exceed the supply rails by more than 0.5 V should be current-limited to 10 mA or less. |
| 5 | V+ | power_in | Positive (highest) power supply; the supply Vs=(V+)-(V-) is 2.1 V to 5.5 V recommended with a 7 V absolute maximum. |
