FN6379.0
Ultra Low ON-Resistance, Low-Voltage,
Single Supply, Differential 4 to 1 Analog
Multiplexer
The Intersil ISL54057 device contains precision, bidirectional,
analog switches configured as a differential 4-channel
multiplexer/demultiplexer, designed to operate from a single
+1.6V to +3.6V supply. The devices have an inhibit pin to
simultaneously open all signal paths.
ON resistance is 0.41鈩?with a +3V supply and 0.61鈩?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擄C or 35nA max at +85擄C with a +3.3V supply.
All digital inputs are 1.8V logic-compatible when using a
single +3V supply.
The ISL54057 is a differential 4 to 1 multiplexer device that is
offered in a 16 Ld 2.6x1.8x0.5mm
碌TQFN
package.
Table 1 summarizes the performance of this family.
