GENERAL DESCRIPTION

The ADG601/ADG602 are monolithic, CMOS single-pole

single-throw (SPST) 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 replacements for mechanical relays because they are more

reliable, have lower power requirements, and are available in

much smaller package sizes.

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

is a normally closed (NC) switch. Each switch conducts equally

well in both directions when the device is on, with the input

signal range extending to the supply rails.

The switches are available in tiny, 6-lead SOT-23; 8-lead MSOP;

and 820 μm × 2255 μm die.
