AD8600
T he functionality of this circuit is shown in the scope photo in
Figure 24 T he top trace is the control ramp, which goes from
0 V to 1.25 V. T he bottom trace is the output of the AD600.
T he input is actually a 12 mV p-p, 10 kHz sine wave. T hus, the
bottom trace shows the envelop of this waveform to illustrate
the increase in gain as time progresses. T his ramp was gener-
ated under control of the 68HC11 using the “ramp” subroutine
as mentioned above. T he slope of the ramp can easily be
lengthened by adding some delay in the loop, or the slope can
be increased by stepping by 2 or more LSBs instead of the cur-
rent 1 LSB changes.

Glitch Impulse
A specification of interest in many DAC applications is the
glitch impulse. T his is the amount of energy contained in any
overshoot when a DAC changes at its major carry transition, in
other words, when the DAC switches from code 01111111 to
code 10000000. T his point is the most demanding because all
of the R-2R ladder switches are changing state. T he AD8600’s
glitch impulse is shown in Figure 25. Calculating the value of
the glitch is accomplished by calculating the area of the pulse,
which for the AD8600 is: Glitch Impulse = (1/2)
