FUNCTIONAL BLOCK DIAGRAM

GENERAL DESCRIPTION

The ADG621, ADG622, and the ADG623 are monolithic,
CMOS SPST (single-pole, single-throw) switches. Each switch
of the ADG621, ADG622, and ADG623 conducts equally well
in both directions when on.

The ADG621/ADG622/ADG623 contain two independent
switches. The ADG621 and ADG622 differ only in that both

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. Tiny 10-Lead µSOIC Package

switches are normally open and normally closed respectively. In the
ADG623, Switch 1 is normally open and Switch 2 is normally
closed. The ADG623 exhibits break-before-make switching action.

The ADG621/ADG622/ADG623 offers low on-resistance of
4 Ω, which is matched to within 0.25 Ω between channels.
These switches also provide low power dissipation yet gives
high switching speeds. The ADG621, ADG622, and ADG623
are available in a 10-lead µSOIC package.

NOTES

1

Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent 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 ADG621/ADG622/ADG623 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.
