8 Detailed Description

8.1 Overview

The TS3A44159 is a bidirectional 4-channel single-pole double-throw (SPDT) analog switch with two control inputs, which is designed to operate from 1.65 V to 4.3 V. This device is also known as a 2-channel, double-pole, double-throw (DPDT) configuration. It offers low ON-state resistance and excellent ON-state resistance matching with the break-before-make feature that prevents signal distortion during the transferring of a signal from one channel to another. The device has an excellent total harmonic distortion (THD) performance and consumes very low power. These features make this device suitable for portable audio applications.

8.3 Feature Description

The TS3A44159 is a bidirectional device that has two sets of two single-pole double-throw switches. The four channels of the switch are contorled by two digital signals; one digital contorl for each set of two single-pole double-throw switches.
