GS358A-MR from Gainsil, in a MSOP-8. 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 | Amplifier A output with rail-to-rail swing, specified for loads down to 10Ω with 84mA typ source and 75mA typ sink current at 5V. |
| 2 | INA- | input | Amplifier A inverting input, rail-to-rail with common-mode range of VSS-0.1V to VDD+0.1V and absolute maximum of VSS-0.5V to VDD+0.5V. |
| 3 | INA+ | input | Amplifier A non-inverting input, rail-to-rail with common-mode range of VSS-0.1V to VDD+0.1V and absolute maximum of VSS-0.5V to VDD+0.5V. |
| 4 | VSS | power_in | Negative supply or ground; for dual-supply operation of ±1.05V to ±2.75V it should be bypassed with a 0.1µF ceramic capacitor. |
| 5 | INB+ | input | Amplifier B non-inverting input, rail-to-rail with common-mode range of VSS-0.1V to VDD+0.1V and absolute maximum of VSS-0.5V to VDD+0.5V. |
| 6 | INB- | input | Amplifier B inverting input, rail-to-rail with common-mode range of VSS-0.1V to VDD+0.1V and absolute maximum of VSS-0.5V to VDD+0.5V. |
| 7 | OUTB | output | Amplifier B output with rail-to-rail swing, specified for loads down to 10Ω with 84mA typ source and 75mA typ sink current at 5V. |
| 8 | VDD | power_in | Positive supply for 2.1V to 5.5V operation (absolute maximum 7.5V between VDD and VSS), with a 0.1µF ceramic capacitor placed close to the pin. |
