ISL84782
FN6097.3
Ultra Low ON-Resistance, Low-Voltage,
Single Supply, Differential 4 to 1 Analog
Multiplexer
The Intersil ISL84782 device contains precision, bidirectional,
analog switches configured as a differential 4-channel
multiplexer/demultiplexer. It is designed to operate from a
single +1.6V to +3.6V supply. The device has an inhibit pin to
simultaneously open all signal paths.
ON resistance is 0.5⦠with a +3V supply and 0.62⦠with a
single +1.8V supply. Each switch can handle rail to rail
analog signals. The off-leakage current is only 4nA max at
+25°C and 30nA max at +85°C with a +3.3V supply.
All digital inputs are 1.8V logic-compatible when using a
single +3V supply.
The ISL84782 is a differential 4 to 1 multiplexer device that is
offered in a 16 Ld TSSOP package and a 16 Ld thin QFN
package.
Table 1 summarizes the performance of this family.
