Low-Voltage, Dual DPDT/Quad SPDT
Analog Switches in QFN
General Description
The MAX4699/MAX4701/MAX4702 are low-voltage,
single-supply CMOS analog switches. The MAX4699/
MAX4701 are dual double-pole/double-throw (DPDT)
switches with two control inputs that control two
single-pole/double-throw (SPDT) switches each. The
MAX4702 is a quad SPDT switch with one control input
and one low-voltage digital logic power supply.
These devices operate from a single +1.8V to +5.5V
power supply. When powered from a +2.7V supply the
MAX4699/MAX4701/MAX4702 offer a 75鈩?on-resis-
tance (R
ON
), with 12鈩?max R
ON
flatness and 4鈩?max
matching between channels. Each switch has Rail-to-
Rail廬 signal handling, fast switching speeds of t
ON
=
35ns, t
OFF
= 20ns, and a maximum 1nA of leakage cur-
rent.
The MAX4699/MAX4701 digital inputs are 1.8V-logic
compatible when operated from a +3V supply. The
MAX4702鈥檚 digital inputs feature a 1.0V threshold when
powered with a 1.5V logic supply.
The MAX4699 is available in a space-saving 16-lead
4mm x 4mm QFN package. The MAX4701/MAX4702
are available in space-saving 16-lead 3mm x 3mm QFN
and 16-pin TSSOP packages.
