RS621BXF-Q1 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 | +IN | input | Positive (noninverting) op-amp input. Rail-to-rail input range from V- to V+; input voltage range -0.1 V to +5.6 V with Vs = 5.5 V. |
| 2 | V- | power_in | Negative (lowest) power supply / ground reference. Total supply range V+ to V- of 2.5 V to 5.5 V; commonly tied to GND for single-supply operation. |
| 3 | -IN | input | Negative (inverting) op-amp input. Rail-to-rail input range from V- to V+. |
| 4 | OUT | output | Op-amp output. Rail-to-rail output swings from V- to V+ under load. |
| 5 | V+ | power_in | Positive (highest) power supply. Supply range 2.5 V to 5.5 V (referenced to V-). Bypass with a local decoupling capacitor to V-. |
