In the circuit of Figure 13, the AD7628 is used to implement a
programmable window comparator. DACs A and B are loaded
with the required upper and lower voltage limits for the test,
respectively. If the test input is not within the programmed lim-
its, the pass/fail output will indicate a fail (logic zero).
In this state, variable or universal filter configuration (Figure
14) for DACs A1 and B1 control the gain and Q of the filter
characteristic, while DACs A2 and B2 control the cutoff fre-
quency, fC. DACs A2 and B2 must track accurately for the simple
expression for fC to hold. This is readily accomplished by the
AD7628. Op amps are 2
× AD644. C3 compensates for the
effects of op amp gain-bandwidth limitations.
The filter provides low pass, high pass and band pass outputs
and is ideally suited for applications where microprocessor con-
trol of filter parameters is required, e.g., equalizer, tone con-
trols, etc.
Programmable range for component values shown is fC = 0 kHz
to 15 kHz and Q = 0.3 to 4.5.
