RS6331KXF from Jiangsu RUNIC Tech, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Amplifier output. Rail-to-rail; typical output current source ~110mA, short-circuit protected (continuous short-to-ground per absolute-max notes; limit current to 140mA). |
| 2 | V- | power_in | Negative (lowest) power supply rail. In single-supply operation tie to GND; supports dual-supply operation down to -2.75V. Vs = (V+)-(V-) must be 2.1V to 5.5V (7V absolute max). |
| 3 | +IN | input | Non-inverting (positive) amplifier input. Rail-to-rail input; common-mode range extends from (V-)-0.2V to (V+)+0.2V at Vs=5.5V. Input bias current ~1pA typ, 10pA max at 25degC. Diode-clamped to supply rails; limit input current to +/-10mA. |
| 4 | -IN | input | Inverting (negative) amplifier input. Rail-to-rail input; common-mode range extends from (V-)-0.2V to (V+)+0.2V at Vs=5.5V. Diode-clamped to supply rails; limit input current to +/-10mA. |
| 5 | V+ | power_in | Positive (highest) power supply rail. Operating range 2.1V to 5.5V single-supply (or up to +2.75V dual-supply). 7V absolute maximum across V+ to V-. Quiescent current ~85uA typ, 145uA max. |
