Stereo Source Selector:
A single logic signal controls the status of all four switches of
the device, simplifying stereo source switching.
The low on-resistance (<35 W) minimizes total harmonic
distortion.
Dual Slope Integrators:
ein
The DG403 is well suited to configure a selectable slope
integrator. One control signal selects the timing capacitor
C1 or C2. Another one selects ein 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.
