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
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
ON/tOFF
.
5. Tiny, 8-lead SOT-23 and 8-lead MSOP.
