An LED driver that will sequentially light ten LEDs when a gradually increasing voltage is applied to pin 5, (dot mode) or in bar mode all LEDs indicating voltages below input are lit. In dot mode there is a slight overlap so that at no point are all LEDs extinguished. A brightness control will set LED current between 2mA and 30mA. The drivers are stackable and displays with 100 or more LEDs are possible. Supply voltage 3V to 18V. The driver that sets the indication points can be referenced to a wide range of voltages. The LM3914 is available with linear steps.
