GENERAL DESCRIPTION
Table I. Truth Table for the ADG619/ADG620
The ADG619 and the ADG620 are monolithic, CMOS SPDT
(single pole, double throw) switches. Each switch conducts
equally well in both directions when on.

The ADG619/ADG620 offers low On-Resistance of 4 Ω, which
is matched to within 0.7 Ω between channels. These switches also
provide low power dissipation yet give high switching speeds.The
ADG619 exhibits break-before-make switching action, thus
preventing momentary shorting when switching channels. The
ADG620 exhibits make-before-break action.
The ADG619/ADG620 are available in 8-lead SOT-23 packages and 8-lead Micro-SOIC packages.
PRODUCT HIGHLIGHTS
1. Low On Resistance (RON) (4 Ω typ)
2. Dual ± 2.7 V to ± 5.5 V or Single 2.7 V to 5.5 V
3. Low Power Dissipation. CMOS construction ensures low
power dissipation.
4. Fast tON/tOFF
5. Tiny 8-Lead SOT-23 Package and 8-Lead Micro-SOIC Package

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability. Only one absolute
maximum rating may be applied at any one time.
2
Overvoltages at IN, S or D will be clamped by internal diodes. Current should be
limited to the maximum ratings given.

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 ADG619/ADG620 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.
