GS8621-TR from Gainsil, in a SOT-23-5. 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 with rail-to-rail swing, able to drive heavy loads (53 mA typical output current at 5V). |
| 2 | VSS | power_in | Negative supply pin, connected to ground in single-supply operation; the supply range VDD to VSS is 2.1V to 5.5V. |
| 3 | IN+ | input | Non-inverting input with rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V) and an absolute maximum input voltage of VSS-0.5V to VDD+0.5V. |
| 4 | IN- | input | Inverting input with rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V) and an absolute maximum input voltage of VSS-0.5V to VDD+0.5V. |
| 5 | VDD | power_in | Positive supply pin, operating from 2.1V to 5.5V (absolute maximum 7.5V relative to VSS), with a 0.1uF ceramic bypass capacitor placed close to it. |
