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.
