An auxiliary current source at pin 1 keeps at least ? Current flowing out of the reference. One pin changes the Display from a bar graph to a moving dot Display LED current drive is regulated and programmable, eliminating the need for current limiting resistors. In order for display to make sense when multiple drivers are.

However, any reference loading adds. The LM’s outputs correspond to the meter. Audio applications include average or peak level indicators. At the low end of the intensity adjustment, the voltage drop. LED intensity must be adjusted independently over a wide. Current flowing out of the signal input.
