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
on-resis-
tance (R
ON
), with 12
max R
ON
flatness and 4
max
matching between channels. Each switch has Rail-to-
Rail® 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's 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.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
