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.
