GENERAL DESCRIPTION

The ADG801 and ADG802 are monolithic CMOS, single-pole,

single throw (SPST) switches with on resistance of less than 0.4 Ω.

These switches are designed using an advanced submicron process

that provides extremely low on resistance, high switching speed,

and low leakage currents.

The low on resistance of <0.4 Ω makes these parts ideal for

applications where low on resistance switching is critical.

The ADG801 switch is normally open (NO), while the ADG802

is normally closed (NC). Each switch conducts equally well in

both directions when on.

PRODUCT HIGHLIGHTS

1. Low on resistance (0.25 Ω typical).

2. 1.8 V to 5.5 V single-supply operation.

3. Tiny 6-lead SOT-23 and 8-lead MSOP packages.

4. 400 mA current-carrying capability.

5. Automotive temperature range from −40°C to +125°C.

6. Pin compatible with ADG701 (ADG801) and ADG702

(ADG802).
