The analog input voltage can vary from 3V to 18V and the LED current can be limited by simply using a single resistor on pin 7 (Ref Out). The IC also has two operating modes DOT mode and BAR mode, also more than one IC can be cascaded to control upto 100 LEDs. Since the LEDs can be controlled without any flickering and flawlessly with equal brightness these IC�s are commonly used in visual alarms and other metering/monitoring applications. So, if you are looking for an IC to driver your bar LED lights or other sequence of 10 LED then this IC might be of interest to you.
