This switch PRODUCT HIGHLIGHTS is designed on a submicron process that provides low power 1. 1.8 V to 5.5 V Single-Supply Operation. The ADG749 dissipation yet gives high switching speed, low on resistance, offers high performance, including low on resistance and and low leakage currents. fast switching times, and is fully specified and guaranteed The ADG749 can operate from a single-supply range of 1.8 V to with 3 V and 5 V supply rails. 5.5 V, making it ideal for use in battery-powered instruments 2. Very Low RON (5 Maximum at 5 V and 10 Maximum and with the new generation of DACs and ADCs from Analog at 3 V). At 1.8 V operation, R is typically 40 over the ON Devices, Inc. temperature range. Each switch of the ADG749 conducts equally well in both 3. Automotive Temperature Range: 40C to +125C. directions when on. The ADG749 exhibits break-before-make 4. On Resistance Flatness (R ) (0.75 typical). FLAT(ON) switching action. 5. 3 dB Bandwidth > 200 MHz. Because of the advanced submicron process, 3 dB bandwidths of greater than 200 MHz can be achieved. 6. Low Power Dissipation. CMOS construction ensures low power dissipation. The ADG749 is available in a 6-lead SC70 package. 7. Fast tON/tOFF. 8. Tiny, 6-lead SC70 Package. Rev. C Information furnished by Analog Devices is believed to be accurate and reliable.
