**Texas Instruments** · Operational Amplifier · SOIC-8

LMP2232BMAE from Texas Instruments, in a SOIC-8. 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 A | output | Amplifier A output, rail-to-rail swinging within 15 mV of the supply voltage. |
| 2 | IN A- | input | Amplifier A inverting input, CMOS high-impedance input with input bias current of about 20 fA; differential input voltage limited to ±300 mV. |
| 3 | IN A+ | input | Amplifier A non-inverting input, common mode range extends 200 mV below the negative supply; differential input voltage limited to ±300 mV. |
| 4 | V- | power_in | Negative supply (ground in single-supply use); supply voltage V+ - V- is 1.6V to 5.5V with a 6V absolute maximum. |
| 5 | IN B+ | input | Amplifier B non-inverting input, common mode range extends 200 mV below the negative supply; differential input voltage limited to ±300 mV. |
| 6 | IN B- | input | Amplifier B inverting input, CMOS high-impedance input with input bias current of about 20 fA; differential input voltage limited to ±300 mV. |
| 7 | OUT B | output | Amplifier B output, rail-to-rail swinging within 15 mV of the supply voltage. |
| 8 | V+ | power_in | Positive supply; operating range 1.6V to 5.5V (V+ - V-) with a 6V absolute maximum. |
