Application Information
Dual Slope Integrators
The DG403 is well suited to configure a selectable slope
integrator. One control signal selects the timing capacitor C
1
or C
2
. Another one selects e
IN
or discharges the capacitor in
preparation for the next integration cycle.
Peak Detector
A
3
acting as a comparator provides the logic drive for
operating SW
1
. The output of A
2
is fed back to A
3
and
compared to the analog input e
IN
. If e
IN
> e
OUT
the output
of A
3
is high keeping SW
1
closed. This allows C
1
to charge
up to the analog input voltage. When e
IN
goes below e
OUT
,
A
3
goes negative, turning SW
1
off. The system will therefore
store the most positive analog input experienced.
