Hello
I need to get a linear voltage from the NPN output of the LM3914.
I verify that the output voltage is not linear but exponential.
Note: the resistor that is connected to 0v, instead of is connected to 10v.
The leds is configured in dot mode.
What is the best way to get a linear voltage for the LED that is on? I know that if you use resistors of 1k 2k 4k 8k 16k 32k ... it is possible to keep the voltage linear but since there are many resistors I intend to use equal values.
Thank you
