ISL43840IRZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43840IRZ-T is a dual, bidirectional analog switch configured as two independent SP4T multiplexers. It operates on a single supply voltage ranging from 2.7V to 12V or dual supplies of ±2V to ±6V. The device features a maximum on-resistance of 50 ohms with channel-to-channel matching of 1.3 ohms. Key electrical specifications include a charge injection of 0.3pC and off-state leakage current of 100pA maximum. Crosstalk is specified at -110dB at 100kHz. The component is housed in a 20-VFQFN package with exposed pad and supports an operating temperature range of -40°C to 85°C.
