Truth Table The ADG601/ADG602 are monolithic CMOS SPST (Single Pole, Single Throw) switches with On Resistance typically less than 2.5 . The Low On Resistance flatness makes the ADG601/ ADG602 ideally suited to many applications, particularly those requiring low distortion. These switches are ideal for replacements for mechanical relays because they are more reliable, have lower power requirements, and package size is much smaller. PRODUCT HIGHLIGHTS 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. 1. 2. 3. 4.

CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADG601/ADG602 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. -4- WARNING!
