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 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. 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 and normally closed respectively. While in the ADG723, Switch 1 is normally open and Switch 2 is normally closed. 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. The ADG721, ADG722 and ADG723 offers high performance, including low on resistance and fast switching times and is fully speci- fied and guaranteed with +3 V and +5 V supply rails. 2. Very Low RON (4 Ω max at 5 V, 10 Ω max at 3 V). At 1.8 V operation, RON is typically 40 Ω over the temperature range. 3. Low On-Resistance Flatness. 4. –3 dB Bandwidth >200 MHz. 5. Low Power Dissipation. CMOS construction ensures low power dissipation. 6. Fast tON/tOFF. 7. 8-Lead µSOIC. |
