LM3914 VS LM3915 VS LM3916[Video]: What are the differences between them?

• The LM3914 is a monolithic integrated circuit that detects analog voltage levels and operates ten LEDs to create a linear analog display. With a single pin, the display transforms from a moving dot to a bar graph. The LEDs' current drive is regulated and customizable, removing the need for resistors. This is a feature that allows the entire system to run on less than 3V.

• As an analog meter circuit, the LM3914 is fairly simple to use. In addition to the 10 display LEDs, a 1.2V full-scale meter requires only 1 resistor and a single 3V to 15V supply.

• The LM3914 has a temperature range of 0°C to +70°C. An 18-lead PDIP (NFK) package is available for the LM3914N-1.

• The LM3915 is a monolithic integrated circuit that senses analog voltage levels and drives ten LEDs, LCDs, or vacuum fluorescent displays to provide a 3 dB/step analog display. The display switches from a bar graph to a moving dot display with the flip of a pin. Current limiting resistors are not required because the LED current drive is regulated and programmable. A single supply of as little as 3V or as high as 25V can power the entire display system.

• The LM3915 is a multifunctional device. LCDs, vacuum fluorescents, incandescent bulbs, and LEDs of any color can all be driven by the outputs.

• The LM3915 is very simple to use. In addition to the ten LEDs, a 1.2V full-scale meter just requires one resistor. One more resistor programs the full-scale anywhere from 1.2V to 12V independent of the supply voltage.

• The LM3916 is very simple to use. In addition to the ten LEDs, a 1.2V fullscale meter just requires one resistor. A final resistor sets the full scale to any voltage between 1.2 and 12 volts, regardless of the supply voltage. A single pot can easily control the brightness of LEDs.

• The LM3916 has a wide range of applications. LCDs, vacuum fluorescents, incandescent bulbs, and LEDs of any color can all be driven by the outputs. For improved range and/or resolution, multiple devices can be cascaded to create a dot or bar style display. The linear LM3914 and logarithmic LM3915 are useful in numerous applications.
