ADG749BKSZ-REEL
CMOS 1.8 V至5.5 V , 2.5欧姆2 : 1多路复用器,SC70封装/ SPDT开关 CMOS 1.8 V to 5.5 V, 2.5 ohm 2:1 Mux/SPDT Switch in SC70 Package
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 RFLATON 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.
