MAX4091ASA+ from Maxim Integrated, in a SOIC-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 | N.C. | unconnected | No connection; the pin is not internally connected. |
| 2 | IN- | input | Inverting input; the input common-mode range extends 50mV beyond the supply rails, and the outputs are guaranteed not to phase-reverse or latch up beyond the common-mode range. |
| 3 | IN+ | input | Noninverting input; the input common-mode range extends 50mV beyond the supply rails (VEE - 0.05V to VCC + 0.05V). |
| 4 | VEE | power_in | Negative supply; the device operates from a single 2.7V to 6V supply with VEE as ground, or from split supplies of ±1.35V to ±3V. |
| 5 | N.C. | unconnected | No connection; the pin is not internally connected. |
| 6 | OUT | output | Amplifier output; swings to within 15mV of the supplies with a 100kΩ load and drives 1kΩ loads, with stability maintained for capacitive loads above 2000pF. |
| 7 | VCC | power_in | Positive supply; operating range is 2.7V to 6V referenced to VEE, with a 0.1µF bypass capacitor recommended for single-supply operation. |
| 8 | N.C. | unconnected | No connection; the pin is not internally connected. |
