GS6551-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 deliver 65mA output current (60mA short-circuit limit) per the electrical characteristics. |
| 2 | VSS | power_in | Negative supply (ground in single-supply operation); input common-mode range extends to VSS-0.1V and supply range VDD to VSS is 1.8V to 5.5V. |
| 3 | IN+ | input | Non-inverting input, rail-to-rail with a common-mode range of VSS-0.1V to VDD+0.1V and an absolute maximum of VSS-0.5V to VDD+0.5V. |
| 4 | IN- | input | Inverting input, rail-to-rail with a common-mode range of VSS-0.1V to VDD+0.1V and an absolute maximum of VSS-0.5V to VDD+0.5V. |
| 5 | VDD | power_in | Positive supply, 1.8V to 5.5V single supply (7.5V absolute maximum VDD to VSS), bypassed with a 0.1µF ceramic capacitor placed close to the pin. |
