MAX4291EXK+T from Analog Devices Inc Maxim Integrated, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN+ | input | Noninverting op-amp input. Rail-to-rail common-mode range (VEE to VCC). Input is protected by an internal 10.6kΩ series resistor and back-to-back triple-diode stack to IN-. |
| 2 | VEE | power_in | Negative supply rail. Connect to ground for single-supply operation (1.8V to 5.5V total), or to a negative rail for dual-supply operation (±0.9V to ±2.75V). Bypass with a 100nF capacitor. |
| 3 | IN- | input | Inverting op-amp input. Rail-to-rail common-mode range (VEE to VCC). Input is protected by an internal 10.6kΩ series resistor and back-to-back triple-diode stack to IN+. |
| 4 | OUT | output | Amplifier output. Rail-to-rail output stage swings to within 46mV of either supply rail with a 2kΩ load to VCC/2. Unity-gain stable for capacitive loads up to 100pF; typical output short-circuit current is 20mA. |
| 5 | VCC | power_in | Positive supply rail. 1.8V to 5.5V single-supply operation (referenced to VEE = GND), or +0.9V to +2.75V in dual-supply configuration. Bypass to VEE with a 100nF capacitor placed close to the pin. |
