ADA4891-1ARJZ-R7 from Analog Devices, 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, a rail-to-rail stage that swings to within 50 mV of each supply rail. |
| 2 | -VS | power_in | Negative supply; the single-supply range is 2.7 V to 5.5 V total, and the input common-mode range extends 300 mV below -VS. |
| 3 | +IN | input | Non-inverting input; the input common-mode voltage range is -VS - 0.3 V to +VS - 0.8 V. |
| 4 | -IN | input | Inverting input; stray capacitance on this node forms a pole with the feedback and gain resistors and causes peaking, so it should be kept small and placed close to the device. |
| 5 | +VS | power_in | Positive supply; operates from 2.7 V to 5.5 V with an absolute maximum of 6 V. |
