1.25V ≤ V
1.5 mA ≤ I
Optional circuit for improved intensity matching at low currents. See text.
Other Applications
For increased resolution, it’s possible to obtain a display with
a smooth transition between LEDs. This is accomplished by
superimposing an AC waveform on top of the input level as

shown in Figure 14. The signal can be a triangle, sawtooth or
sine wave from 60 Hz to 1 kHz. The display can be run in
either dot or bar mode.
