LMC7221BIM5X from Texas Instruments, in a SOT-23-5. 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 | OUTPUT | output | Open-drain comparator output; can be pulled up via external resistor to a voltage above or below the supply, up to 15V, with output current up to 30mA absolute max and 40mA short-circuit current. |
| 2 | V+ | power_in | Positive supply voltage input, operating range 2.7V to 15V. |
| 3 | NON-INVERTING INPUT | input | Non-inverting (+) comparator input with rail-to-rail common-mode range extending slightly beyond V- and V+; input current 0.04pA typical. |
| 4 | INVERTING INPUT | input | Inverting (-) comparator input with rail-to-rail common-mode range extending slightly beyond V- and V+; input current 0.04pA typical. |
| 5 | V- | power_in | Negative supply/ground pin, referenced as 0V in electrical characteristics tables. |
