Gainsil · Operational Amplifier · SOT-23-5
GS8045-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, typically within 50mV of the supply rail under light resistive loads (>50kΩ); the datasheet notes it is not optimized for capacitive loads, so an isolation resistor is recommended for those. |
| 2 | VSS | power_in | Negative supply pin (ground in single-supply operation), with the device operating from 1.4V to 5.5V across VDD to VSS and absolute maximum VDD-to-VSS of 7.5V. |
| 3 | IN+ | input | Non-inverting input whose common-mode range extends 100mV beyond the rails (VSS-0.1V to VDD+0.1V), with analog input voltage absolute limits of VSS-0.5V to VDD+0.5V. |
| 4 | IN- | input | Inverting input with the same common-mode range (VSS-0.1V to VDD+0.1V) and analog input absolute limits of VSS-0.5V to VDD+0.5V; inputs should be kept within the common-mode range for normal operation. |
| 5 | VDD | power_in | Positive supply pin (1.4V to 5.5V operating), where a 0.1µF ceramic bypass capacitor should be placed close to the pin in single-supply operation. |
