APPLICATIONS

Dual Slope Integrators

The DG403B is well suited to configure a selectable slope

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 DG403B allow for

higher clock rates and consequently higher filter operating

frequencies.
