Overview
The TS5A3153 is a single-pole double-throw (SPDT) analog switch designed by Texas Instruments. This device operates from a wide voltage range of 1.65 V to 5.5 V, making it versatile for various applications. It features low ON-state resistance, excellent on-resistance matching, and a break-before-make switching mechanism to prevent signal distortion. The TS5A3153 is also known for its low power consumption, low charge injection, and high total harmonic distortion (THD) performance, making it suitable for portable audio and other signal routing applications.
