LM3914 or LM3916

Wan't drive a 10-led bargraph with arduino.

What is the best solution a LM3914 or a LM3916 ?

Ledbargraph DC-7G3HWA from Kingbright.

I work with 5V !

What do you mean by best?

Don't know should i use the LM3914 or the LM3916 ?

Depends on what your application is.

The LM3914 is a liner display, that is each bar has the same voltage increment. The LM3916 is calibrated in dBs and so is basically a logarithmic display.
