APPLICATIONS
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 DG333A/333AL allow for higher
clock rates and consequently higher filter operating
frequencies. Figure 8 shows two capacitors being switched.
The DG333A/333AL is capable of switching four capacitors.
