GS8045-TR

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.
