LM3914
Dot/Bar Display Driver
General Description
The LM3914 is a monolithic integrated circuit that senses
analog voltage levels and drives 10 LEDs, providing a linear
analog display. A single pin changes the display from a
moving dot to a bar graph. Current drive to the LEDs is
regulated and programmable, eliminating the need for resis-
tors. This feature is one that allows operation of the whole
system from less than 3V.
The circuit contains its own adjustable reference and accu-
rate 10-step voltage divider. The low-bias-current input
buffer accepts signals down to ground, or V
?
, yet needs no
protection against inputs of 35V above or below ground. The
buffer drives 10 individual comparators referenced to the
precision divider. Indication non-linearity can thus be held
typically to
1
?2%, even over a wide temperature range.
Versatility was designed into the LM3914 so that controller,
visual alarm, and expanded scale functions are easily added
on to the display system. The circuit |
