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