GENERAL DESCRIPTION
The ADG661, ADG662 and ADG663 are monolithic CMOS
devices comprising four independently selectable switches.
These switches feature low, well-controlled on resistance and
wide analog signal range, making them ideal for precision analog
signal switching.
They are fabricated using Analog Devices' advanced linear
compatible CMOS (LC2MOS) process, which offers benefits of
low leakage currents, ultralow power dissipation and low capaci-
tance for fast switching speeds with minimum charge injection.
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 make the parts suitable for video signal
switching. CMOS construction ensures ultralow power dissipa-
tion making the parts ideally suited for portable and battery
powered instruments.
The ADG661, ADG662 and ADG663 contain four indepen-
dent SPST switches. The ADG661 and ADG662 differ only in
that the digital control logic is inverted. The ADG661 switches
are turned on with a logic low on the appropriate control input,
while a logic high is required for the ADG662. The ADG663
has two switches with digital control logic similar to that of the
ADG661, while the logic is inverted on the other two switches.
Each switch conducts equally well in both directions when ON
and has an input signal range that extends to the supplies. In the
OFF condition, signal levels up to the supplies are blocked. All
switches exhibit break-before-make switching action for use in
multiplexer applications. Inherent in the design is low charge
injection for minimum transients when switching the digital
inputs.
PRODUCT HIGHLIGHTS
1. +5 V Single Supply Operation
The ADG661, ADG662 and ADG663 offer high perfor-
mance, including low on resistance and wide signal range,
fully specified and guaranteed with ± 5 V and +5 V supply
rails.
2. Ultralow Power Dissipation
CMOS construction ensures ultralow power dissipation.
3. Low RON
4. Break-Before-Make Switching
This prevents channel shorting when the switches are config-
ured as a multiplexer.
