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