# MAX4412EUK+T

**Maxim Integrated** · Operational Amplifier · SOT-23-5

MAX4412EUK+T from Maxim Integrated, 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, which swings to within 105mV of either power-supply rail with a 1kΩ load. |
| 2 | VEE | power_in | Negative power supply; the amplifier operates from a single +2.7V to +5.5V supply with VEE as the reference (ground) rail. |
| 3 | IN+ | input | Amplifier noninverting input; the input common-mode range extends from (VEE - 0.1V) to (VCC - 1.5V). |
| 4 | IN- | input | Amplifier inverting input; the input common-mode range extends from (VEE - 0.1V) to (VCC - 1.5V). |
| 5 | VCC | power_in | Positive power supply; bypass VCC to ground with a 0.1µF capacitor as close to the pin as possible. |
