Ultra Low ON-Resistance, Single Supply,
Differential SPST Analog Switches
The Intersil ISL43L710, ISL43L711, ISL43L712 devices are
low ON-resistance, low voltage, bidirectional, precision,
differential single-pole/single-throw (SPST) analog switches
designed to operate from a single +1.65V to +3.6V supply.
Targeted applications include battery powered equipment
that benefit from low R_ON (0.16Ω), low power consumption
(0.12μW) and fast switching speeds (t_ON = 13ns,
t_OFF = 13ns).
Cell phones, for example, often face ASIC functionality
limitations. The number of analog input or GPIO pins may be
limited and digital geometries are not well suited to analog
switch performance. This family of parts may be used to
switch in additional functionality while reducing ASIC design
risk. The ISL43L71X are offered in small form factor
packages, alleviating board space limitations.
The ISL43L710, ISL43L711, ISL43L712 are differential
single-pole/single-throw (SPST) devices. The ISL43L710
has two normally open (NO) switches; the ISL43L711 has
two normally closed (NC) switches; the ISL43L712 has one
normally open (NO) and one normally closed (NC) switch
and can be used as an SPDT. The ISL43L712 is equipped
with an inhibit pin to simultaneously open all signal paths.
Table 1 summarizes the performance of this family.
