GENERAL DESCRIPTION

The ADG619/ADG620 are monolithic, CMOS single-pole

double-throw (SPDT) switches. Each switch conducts equally

well in both directions when the device is on.

The ADG619/ADG620 offer a low on resistance of 4 Ω, which

is matched to within 0.7 Ω between channels. These switches

also provide low power dissipation, yet result in 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 an 8-lead SOT-23 and

an 8-lead MSOP.

PRODUCT HIGHLIGHTS

1. Low on resistance (R

): 4 Ω typical.

2. Dual ±2.7 V to ±5.5 V or single 2.7 V to 5.5 V supplies.

3. Low power dissipation.

4. Fast t

OFF

5. Tiny, 8-lead SOT-23 and 8-lead MSOP.
