GENERAL DESCRIPTION

The ADG601/ADG602 are monolithic CMOS SPST (Single

Pole, Single Throw) switches with On Resistance typically less

than 2.5

Ω. The Low On Resistance flatness makes the ADG601/

ADG602 ideally suited to many applications, particularly those

requiring low distortion. These switches are ideal for replace-

ments for mechanical relays because they are more reliable, have

lower power requirements, and package size is much smaller.

The ADG601 is a normally open (NO) switch, while the ADG602

is normally closed (NC). Each switch conducts equally well in

both directions when ON, with the input signal range extending

to the supply rails.

They are available in tiny 6-lead SOT-23 and 8-lead Micro-

SOIC packages.
