The ADG774 is a monolithic CMOS device comprising four 2:1 multiplexer/demultiplexers with high impedance outputs. The CMOS process provides low power dissipation yet gives high switching speed and low on resistance. The on-resistance variation is typically less than 0.5 Ω with an input signal ranging from 0 V to 5 V.
The bandwidth of the ADG774 is greater than 200 MHz and this, coupled with low distortion (typically 0.5%), makes the part suitable for switching fast ethernet signals.
The on-resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion when switching audio signals. Fast switching speed, coupled with high signal bandwidth, also makes the parts suitable for video signal switching. CMOS construction ensures ultralow power dissipation making the parts ideally suited for portable and battery powered instruments.
PRODUCT HIGHLIGHTS
- Wide –3 dB Bandwidth, 240 MHz.
- Ultralow Power Dissipation.
- Extended Signal Range.
The ADG774 is fabricated on a CMOS process giving an increased signal range that fully extends to the supply rails. - Low Leakage Over Temperature.
- Break-Before-Make Switching.
This prevents channel shorting when the switches are configured as a multiplexer. - Crosstalk Typically –70 dB @ 30 MHz.
- Off Isolation Typically –60 dB @ 10 MHz.
APPLICATIONS
- USB 1.1 Signal Switching Circuits
- Cell Phones
- PDAs
- Battery-Powered Systems
- Communications Systems
- Data Acquisition Systems
- Token Ring 4 Mbps/16 Mbps
- Audio and Video Switching
- Relay Replacement
