Overview
The TS3A4751PWR is a 0.9-Ω low-voltage, single-supply, 4-channel single-pole single-throw (SPST) analog switch produced by Texas Instruments. This device operates from a single 1.6-V to 3.6-V supply and is designed for both digital and analog applications. It features fast switching speeds, high current-handling capacity, and very low quiescent power consumption. The TS3A4751PWR is available in 14-pin TSSOP, VQFN, and micro X2QFN packages, making it versatile for various design needs.
