Gainsil · Operational Amplifier · SC-70-5
GS8721-CR from Gainsil, in a SC-70-5. 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 15mV of the supply rail at RL=10kΩ and 100mV at RL=600Ω. |
| 2 | VSS | power_in | Negative supply (ground in single-supply operation); VDD to VSS is rated -0.5V to +7.5V absolute maximum and operates from 2.1V to 5.5V. |
| 3 | IN+ | input | Non-inverting input with rail-to-rail common-mode range of VSS-0.1V to VDD+0.1V and 1pA typical bias current. |
| 4 | IN- | input | Inverting input with rail-to-rail common-mode range of VSS-0.1V to VDD+0.1V and 1pA typical bias current. |
| 5 | VDD | power_in | Positive supply, 2.1V to 5.5V single supply, with a 0.1μF ceramic bypass capacitor placed close to the pin. |
