LM6142AIMX 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 with rail-to-rail swing (about 30mV from the positive rail and 45mV from the negative rail at RL = 100kΩ, VS = 5V typical). |
| 2 | -IN A | input | Inverting input of amplifier A; common-mode range is -0.25V to 5.25V at VS = 5V and the pin is diode-clamped to the supply rails (limit current to 10mA). |
| 3 | +IN A | input | Non-inverting input of amplifier A; common-mode range is -0.25V to 5.25V at VS = 5V and the pin is diode-clamped to the supply rails (limit current to 10mA). |
| 4 | V- | power_in | Negative supply, or ground in single-supply operation; total supply (V+)-(V-) is 2.7V to 32V recommended, with 33V absolute maximum. |
| 5 | +IN B | input | Non-inverting input of amplifier B; common-mode range is -0.25V to 5.25V at VS = 5V and the pin is diode-clamped to the supply rails (limit current to 10mA). |
| 6 | -IN B | input | Inverting input of amplifier B; common-mode range is -0.25V to 5.25V at VS = 5V and the pin is diode-clamped to the supply rails (limit current to 10mA). |
| 7 | OUT B | output | Amplifier B output with rail-to-rail swing (about 30mV from the positive rail and 45mV from the negative rail at RL = 100kΩ, VS = 5V typical). |
| 8 | V+ | power_in | Positive supply; total supply (V+)-(V-) is 2.7V to 32V recommended, with 33V absolute maximum, and typical quiescent current is 650µA per amplifier at 5V. |
