GENERAL DESCRIPTION
The ADG784 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 ADG784 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 switch-
ing audio signals. Fast switching speed, coupled with high signal
bandwidth, also makes the parts suitable for video signal switch-
ing. CMOS construction ensures ultralow power dissipation
making the parts ideally suited for portable and battery powered
instruments.
The ADG784 operates from a single 3.3 V/5 V supply and is
TTL logic compatible. The control logic for each switch is shown
in the Truth Table.
CMOS 3 V/5 V, Wide Bandwidth Quad 2:1
These switches conduct equally well in both directions when
ON, and have an input signal range that extends to the sup-
plies. In the OFF condition, signal levels up to the supplies
are blocked. The ADG784 switches exhibit break-before-
make switching action.
PRODUCT HIGHLIGHTS
1. Also Available as ADG774 in 16-Lead QSOP and SOIC.
2. Wide Bandwidth Data Rates >200 MHz.
3. Ultralow Power Dissipation.
4. Extended Signal Range.
5. Low Leakage over Temperature.
6. Break-Before-Make Switching.
7. Crosstalk is typically –70 dB @ 30 MHz.
8. Off isolation is typically –60 dB @ 10 MHz.
9. Available in Chip Scale Package (CSP).
The ADG784 is fabricated on a CMOS process giving an
increased signal range that fully extends to the supply rails.
This prevents channel shorting when the switches are config-
ured as a multiplexer.
