clocked into the MM5452, MM5453. The next clock pulse
increments the staircase and clocks the new data in.
With a buffer amplifier, the same staircase waveform can be
used for many displays. The digital-to-analog converter need

displayed by using weighted resistors or special DACs. This
system can be used for status indicators, spectrum analyz-
ers, audio level and power meters, tuning indicators, and
other applications.
