Thanks to switch62 for pointing out that technically the LM3914 makes a voltmeter and not a VU meter, because its voltage divider has a linear scale. There are two similar chips, the LM3915 and LM3916 , that are almost exactly the same, but have logarithmically-scaled voltage dividers, corresponding to certain points on a decibel (dB) scale.

Stereo VU-Meter. Besides providing a bar-graph, LM3915 can be also used at “dot” mode. At this specific mode the display changes from a bar graph to a moving dot. The mode of operation depends on S2. When S2 is closed (on), LM3915 provides a bar-graph display. In contrary, the graph changes to a moving dot, when S2 is off. LED VU-Meter
