ty was designed into the HT3914A so that controller, visual alarm, and expanded scale functions are easily added on to the display system. The circuit • Bar or Dot Display Mode Externally Selectable by User can drive LEDs of many colors, or low-current incandescent lamps. Many HT3914A can be • Expandable to Displays of 100 Steps • Internal Voltage Reference from 1.2V to 12V “chained” to form displays of 20 to over 100 segments. Both ends of the voltage divider are externally available so that 2 drivers can be made • Operates with Single Supply of Less than 3V into a zero-center meter.
