MAX4607/MAX4608/

MAX4609

2.5

Ω, Dual, SPST,

CMOS Analog Switches

General Description

The MAX4607/MAX4608/MAX4609 dual analog switches

feature low on-resistance of 2.5

Ω max. On-resistance is

matched between switches to 0.5

Ω max and is flat (0.5Ω

max) over the specified signal range. Each switch can

handle rail-to-rail analog signals. The off-leakage current

is only 2.5nA max at +85°C. These analog switches are

ideal in low-distortion applications and are the preferred

solution over mechanical relays in automatic test equip-

ment or applications where current switching is required.

They have low power requirements, require less board

space, and are more reliable than mechanical relays.

The MAX4607 has two normally closed (NC) switches,

the MAX4608 has two normally open (NO) switches,

and the MAX4609 has one NC and one NO switch.

These switches operate from a single supply of +4.5V to

+36V or from dual supplies of ±4.5V to ±20V. All digital

inputs have +0.8V and +2.4V logic thresholds, ensuring

TTL/CMOS-logic compatibility when using dual ±15V or

a single +12V supply.
