LM4140ACM-1.2
Texas Instruments · Voltage Reference · SOIC-8
LM4140ACM-1.2 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 | Ground | power_in | Negative supply or ground connection that must be connected to ground. |
| 2 | VIN | power_in | Positive supply. |
| 3 | Enable | input | Pulled to input for normal operation; forcing this pin to ground turns off the output. |
| 4 | Ground | power_in | Negative supply or ground connection that must be connected to ground. |
| 5 | NC | unconnected | This pin must be left open. |
| 6 | VREF | power_in | Reference output capable of sourcing up to 8 mA. |
| 7 | Ground | power_in | Negative supply or ground connection that must be connected to ground. |
| 8 | Ground | power_in | Negative supply or ground connection that must be connected to ground. |
