Gainsil · Operational Amplifier · SOT23-5
GS2261-TR from Gainsil, 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; typical output current is 39 mA source and 35 mA sink at VS = 30V. |
| 2 | VSS | power_in | Negative supply rail and reference for the device; the analog input range extends down to VSS, with absolute maximum input at VSS-0.5V. |
| 3 | IN+ | input | Non-inverting input; the common-mode range is 0 to (VS-1.5V) and analog input voltage must stay between VSS-0.5V and VDD+0.5V. |
| 4 | IN- | input | Inverting input; analog input voltage must stay between VSS-0.5V and VDD+0.5V per the absolute maximum ratings. |
| 5 | VDD | power_in | Positive supply, operating from 3.3V to 36V, with an absolute maximum VDD-to-VSS of 40V. |
