LM3914N-1 Frequently Asked Questions (FAQ)
-
R1 and R2 are used to set the full-scale voltage of the device. R1 sets the upper voltage limit, and R2 sets the lower voltage limit. The ratio of R1 to R2 determines the full-scale voltage range.
-
The values of R1 and R2 depend on the desired full-scale voltage range and the voltage reference (Vref) of the LM3914N-1. A good starting point is to choose R1 = 1 kΩ and R2 = 2 kΩ for a 0-10V full-scale range.
-
The Vref pin is used to set the voltage reference for the LM3914N-1. It is typically connected to a stable voltage source, such as a voltage regulator or a voltage reference IC.
-
The LED pins (LED1-10) should be connected to the anodes of the LEDs, and the cathodes should be connected to a current-limiting resistor and then to ground. The resistors should be chosen to limit the current to the desired value for the LEDs.
-
The SIG pin is the input signal pin, which is connected to the voltage being measured. The LM3914N-1 compares the input signal to the internal voltage reference and turns on the corresponding LEDs accordingly.
