ISL43L841
Ultra Low ON-Resistance, Low-Voltage,
Single Supply, Differential 4 to 1 Analog
Multiplexer
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.
All digital inputs are 1.8V logic-compatible when using a
single +3V supply.
The ISL43L841 is a differential 4 to 1 multiplexer device that is
offered in a 16 Ld 3x3 TQFN package.
Table 1 summarizes the performance of this family.
