LTC8551-MS from MSKSEMI, 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 rail to rail. |
| 2 | V- | power_in | Negative (lowest) power supply pin; the single-supply range is 2 V to 5.5 V and the 6 V absolute maximum can permanently damage the amplifier. |
| 3 | +IN | input | Positive (noninverting) input, which supports rail-to-rail common-mode range. |
| 4 | -IN | input | Negative (inverting) input. |
| 5 | V+ | power_in | Positive (highest) power supply pin; the single-supply range is 2 V to 5.5 V and a 0.1 uF capacitor should be placed tightly at this pin. |
