· The internal 10-step divider is floating and can be
referenced to a wide range of voltages.

The LM3914N-1 is an LED Display driver that can drive up to 100 LEDs in Dot Mode or Bar Mode. The current that flows through the LEDs is regulated and programmable, thus, resistors do not need to be implemented. With the elimination of resistors, the whole IC can be operated with less than 3V. The LM3914N-1 (or just LM3914) offers a wide gallery of applications such as:

· 0V to 5V Bar-Graph Meter.

· Cascading LM314s in Dot Mode to produce more LED outputs.

· Zero-Center Meter for 20 Segment Bargraph.

· Expanded Scale Meter Dot Mode or Bar-Graph Mode

· 20 Segment Meter with mode switch ...

· Please refer to the DATA SHEET for more details.
