GENERAL DESCRIPTION  
and normally closed, respectively. In the ADG723, Switch 1 is  
normally open and Switch 2 is normally closed.  
The ADG721, ADG722, and ADG723 are monolithic CMOS  
SPST switches. These switches are designed on an advanced  
submicron process that provides low power dissipation yet gives  
high switching speed, low on resistance, and low leakage  
currents. The devices are packaged in both a tiny 3 mm × 2 mm  
LFCSP and an MSOP, making them ideal for space-constrained  
applications.  
Each switch of the ADG721, ADG722, and ADG723 conducts  
equally well in both directions when on. The ADG723 exhibits  
break-before-make switching action.  
PRODUCT HIGHLIGHTS  
1. 1.8 V to 5.5 V single-supply operation.  
2. Very low RON (4 Ω max at 5 V, 10 Ω max at 3 V).  
3. Low on resistance flatness.  
4. −3 dB bandwidth >200 MHz.  
5. Low power dissipation. CMOS construction ensures low  
power dissipation.  
The ADG721, ADG722, and ADG723 are designed to operate  
from a single 1.8 V to 5.5 V supply, making them ideal for use  
in battery-powered instruments and with the new generation of  
DACs and ADCs from Analog Devices, Inc.  
The ADG721, ADG722, and ADG723 contain two independent  
single-pole/single-throw (SPST) switches. The ADG721 and  
ADG722 differ only in that both switches are normally open  
6. 8-lead MSOP and 3 mm × 2 mm LFCSP.
