APPLICATION BLOCK DIAGRAMS
Figure 1. TS5A22364 Application Block Diagram
Shunt Switch (TS5A22364)
The 50-Ω shunt switches on the TS5A22364 automatically discharge any capacitance at the NC or NO terminals
when they are unconnected to COM. This reduces audible click-and-pop sounds that occur when switching
between audio sources. Audible clicks and pops are caused when a step DC voltage is switched into the
speaker. By automatically discharging the side that is not connected, any residual DC voltage is removed,
thereby reducing the clicks and pops.

Negative Signaling Capacity
The TS5A22362 and TS5A22364 dual SPDT switches feature negative signal capability that allows signals below
ground to pass through without distortion. These analog switches operate from a single +2.3-V to +5.5-V supply.
The input/output signal swing of the device is dependant of the supply voltage V
+
: the devices pass signals as
high as V
+
and as low as V
+
– 5.5 V, including signals below ground with minimal distortion.
Table 1 shows the input/output signal swing the user can get with different supply voltages.
