ISL43L841
Ultra Low ON-Resistance, Low-Voltage, Single Supply, Differential 4 to 1 Analog Multiplexer
FN6212 Rev 1.00 June 30, 2006
The Intersil ISL43L841 device contains precision, bidirectional, analog switches configured as a differential 4-channel multiplexer/demultiplexer. It is designed to operate from a single +1.65V to +4.5V supply. The device has an inhibit pin to simultaneously open all signal paths. With a supply voltage of 4.2V and logic high voltage of 2.85V at the logic inputs, the part draws only 20µA max of ICC current.
ON resistance is 0.47 with a +4.3V supply and 0.65 with a single +1.8V supply. Each switch can handle rail to rail analog signals. A channel can handle 300mA of continuous current. The part has low quiescent power consumption of 0.23µW max.
