Overview
The TS5A3154DCUR is a single-pole double-throw (SPDT) analog switch produced by Texas Instruments. This device is designed to operate 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 channel-to-channel ON-state resistance matching, and low total harmonic distortion (THD), which are crucial for maintaining signal integrity. The TS5A3154DCUR is particularly suitable for portable audio applications, communication circuits, and other low-voltage data-acquisition systems due to its low power consumption and high performance characteristics.
