SGM3699
GENERAL DESCRIPTION
The SGM3699 is a quad, low on-resistance, low voltage,
bidirectional, single-pole/double-throw (SPDT) CMOS
analog switch that is designed to operate from a single
+1.8V to +4.2V power supply. Targeted applications include
battery powered equipment that benefit from low R
ON
(0.5Ω)
and fast switching speeds (t
ON
= 52 ns, t
OFF
= 25 ns).
The SGM3699 consists of four SPDT switches. It is
configured as a dual double-pole/double-throw (DPDT)
device with two logic control inputs that control two SPDT
switches each. The configuration can be used as a dual
differential 2-to-1 multiplexer/demultiplexer.
SGM3699 is available in a TQFN-16 package.
