Figure 10. Dual Slope Integrator
Dual Slope Integrators:
The DG403 is well suited to configure a selectable slope
integrator. One control signal selects the timing capacitor C₁
or C₂. Another one selects e_in or discharges the capacitor in
preparation for the next integration cycle.
Band-Pass Switched Capacitor Filter:
Single-pole double-throw switches are a common element
for switched capacitor networks and filters. The fast
switching times and low leakage of the DG403 allow for
higher clock rates and consequently higher filter operating
frequencies.
