8 Detailed Description

8.1 Overview

The TS5A22364 is a bidirectional 2-channel, single-pole, double-throw (SPDT) analog switch designed to operate from 2.3-V to 5.5-V power supply. The device features negative signal swing capability that allows signals below ground to pass through the switch without distortion. Additionally, the TS5A22364 includes an internal shunt switch, which automatically discharges any capacitance at the NC or NO terminals when they are not connected to COM. Discharging the capacitance reduces the audible click and pop noise when switching between two sources. The break-before-make feature prevents signal distortion during the transferring of a signal from one path to another. Low ON-state resistance, excellent channel-to-channel ON-state resistance matching, and minimal total harmonic distortion (THD) performance are ideal for audio applications.

8.3 Feature Description

8.3.1 Click and Pop Reduction

The shunt resistors in the TS5A22364 automatically discharge any capacitance at the NC or NO terminals when they are not connected to COM. This reduces the 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.

8.3.2 Negative Signal Swing Capability

The TS5A22364 2-channel SPDT switch features 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 and output signal swing of the device is dependant of the supply voltage V_CC. The device passes signals as high as V_CC and as low as V_CC – 5.5 V, including signals below ground with minimal distortion. The OFF state signal path (either NC or NO) during the operation of TS5A22364 cannot handle negative DC voltage

Table 1 shows the input/output signal swing the user can get with different supply voltages.

Table 1. Input/Output Signal Swing

SUPPLY VOLTAGE, V_CC	MINIMUM V_NC, V_NO, V_COM = V_CC - 5.5 V	MAXIMUM V_NC, V_NO, V_COM = V_CC
SUPPLY VOLTAGE, V_CC	ON-STATE SIGNAL PATH
5.5 V	0 V	5.5 V
4.5 V	–1.0 V	4.5 V
3.6 V	–1.9 V	3.6 V
3.0 V	–2.5 V	3.0 V
2.7 V	–2.8 V	2.7 V
2.3 V	-3.2 V	2.3 V
