... The DS4420 exposed paddle is not electrically isolated. It must be soldered to ground for proper operation. Input-Coupling Capacitors The DS4420 is designed to be operated with an AC- coupled input signal. The input resistance, R ciently large to allow the use of small and inexpensive external capacitors. The input resistance combined with the AC-coupling capacitor will create a highpass filter ...
