# GS8052-FR

**Gainsil** · Operational Amplifier · DFN-8-EP(2x2)

GS8052-FR from Gainsil, in a DFN-8-EP(2x2). 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 | OUTA | output | Channel A rail-to-rail output, with 80mA minimum output current at +25C and 0.03V typical swing from the rail at RL=1kΩ. |
| 2 | INA- | input | Channel A inverting input, with an absolute maximum voltage range of Vss-0.5V to VDD+0.5V. |
| 3 | INA+ | input | Channel A non-inverting input, with an absolute maximum voltage range of Vss-0.5V to VDD+0.5V. |
| 4 | VSS | power_in | Negative supply or ground, used with dual supplies of ±1.25V to ±2.75V and bypassed with a 0.1µF ceramic capacitor. |
| 5 | INB+ | input | Channel B non-inverting input, with an absolute maximum voltage range of Vss-0.5V to VDD+0.5V. |
| 6 | INB- | input | Channel B inverting input, with an absolute maximum voltage range of Vss-0.5V to VDD+0.5V. |
| 7 | OUTB | output | Channel B rail-to-rail output, with 80mA minimum output current at +25C and 0.03V typical swing from the rail at RL=1kΩ. |
| 8 | VDD | power_in | Positive supply, operating from 2.5V to 5.5V (absolute maximum 7.5V VDD to Vss) with a 0.1µF ceramic bypass capacitor placed close to the pin. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
