ISL43L680IR

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L680IR is a dual-channel, single-pole double-throw (SPDT) analog switch manufactured by Renesas Electronics Corporation. It operates with a single supply voltage ranging from 2.7V to 5.5V or dual supplies of ±2.7V to ±5.5V. The device features a low on-resistance of typically 1.5Ω and an extremely low charge injection of 0.5pC, ensuring high signal integrity for precision applications. It supports rail-to-rail input and output swing, making it suitable for handling full-scale analog signals. The component is housed in an 8-TDFN package and is specified for operation over an industrial temperature range of -40°C to +85°C.
