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 switches are available in tiny, 6-lead SOT-23; 8-lead MSOP;
and 820 μm × 2255 μm die.

The ADG601 is a normally open (NO) switch, and the ADG602
is a normally closed (NC) switch. Each switch conducts equally
