HT3914A
Description
The individual outputs can drive a transistor The HT3914A is a monolithic integrated circuit that as well as a LED at the same time, so controller senses analog voltage levels and drives 10 LEDs, functions including “staging” control can be providing a linear analog display.
Key Features
- 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
- Operates with Single Supply of Less than 3V into a zero-center meter
- Inputs Operate Down to Ground The HT3914A is very easy to apply as an analog
- Output Current Programmable from 2 mA to 30 meter circuit. A 1.2V full-scale meter requires only 1 mA
- Outputs can Interface with TTL or CMOS Logic and thus any ambiguous display is avoided. Various
Applications
- 0V to 5V Bar Graph Meter
