Texas Instruments · Precision Op Amps · SOT-23-5
LMP2231BMFE from Texas Instruments, 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 | Rail-to-rail amplifier output that swings to within 15 mV of the supply voltage. |
| 2 | V- | power_in | Negative supply (ground in single-supply use); the input common-mode range extends 200 mV below it, with a 1.6V to 5.5V total supply range. |
| 3 | IN+ | input | Non-inverting CMOS input with about 20 fA input bias current and a common-mode range extending 200 mV below V-. |
| 4 | IN- | input | Inverting CMOS input with about 20 fA input bias current and a maximum offset voltage of 150 µV. |
| 5 | V+ | power_in | Positive supply, operating range 1.6V to 5.5V relative to V-. |
