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 75Ω on-resis-

tance (R

), with 12Ω max R

flatness and 4Ω max

matching between channels. Each switch has rail-to-rail

signal handling, fast switching speeds of t

= 35ns,

OFF

= 20ns, and a maximum 1nA of leakage current.

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 TQFN package. The MAX4701/MAX4702

are available in space-saving 16-lead 3mm x 3mm TQFN

16-pin TSSOP packages.
