ST AIRCASE WINDOW COMPARAT OR
In many test systems, it is important to be able to determine
whether some parameter lies within defined limits. T he staircase
window comparator of Figure 18a is a circuit which can be
used, for example, to measure the V
OH
and V
OL
thresholds of a
T T L device under test. Upper and lower limits on both V
OH
and V
OL
can be programmably set using the AD7226. Each ad-
jacent pair of comparators forms a window of programmable
size. If V
T EST
lies within a window then the output for that win-
dow will be high. With a reference of +2.56 V applied to the
V
REF
input, the minimum window size is 10 mV.

Figure 18b. Window Structure
T he circuit can easily be adapted to allow for overlapping of
windows as shown in Figure 19a. If the three outputs from this
circuit are decoded then five different nonoverlapping program-
mable windows can again be defined.

VARY ING RE FE RE NCE SIGNAL
In some applications, it may be desirable to have a varying sig-
nal applied to the reference input of the AD7226. T he AD7226
has multiplying capability within upper and lower limits of refer-
ence voltage when operated with dual supplies. T he upper and
lower limits are those required by the AD7226 to achieve its lin-
earity specification. Figure 20 shows a sine wave signal applied
to the reference input of the AD7226. For input signal frequen-
cies up to 50 kHz the output distortion typically remains less
than 0.1%. T ypical 3 dB bandwidth figure is 700 kHz.
