LM4140BCMX-2.5

Texas Instruments · Voltage Reference · SOIC-8

LM4140BCMX-2.5 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 GND power_in Negative supply or ground connection that must be connected to ground.
2 VIN power_in Positive supply input; the datasheet's Features list low-voltage operation from 1.8 V.
3 Enable input Pulled to input for normal operation; forcing this pin to ground turns off the output.
4 GND 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 GND power_in Negative supply or ground connection that must be connected to ground.
8 GND power_in Negative supply or ground connection that must be connected to ground.
