Part Number:LM3914
I understand the LM3914 is obsolete but I never used it before. I have overheat problem. I use 1k minimum load resistor in series with 5k pot to GND for R1 and 100k pot for R2. I should get 6k resistance for R1 but the highest I get is 3.2k. By the datasheet calculation 3.2k equals 4mA current. The IC overheats quickly and some LEDs go to shutdown. I don't know how to resolve it, lower the current draw.
