GENERAL DESCRIPTION
The ADG1608/ADG1609 are monolithic CMOS analog multip-
lexers comprising eight single channels and four differential
channels, respectively. The ADG1608 switches one of eight
inputs to a common output, as determined by the 3-bit binary
address lines, A0, A1, and A2. The ADG1609 switches one of
four differential inputs to a common differential output, as
determined by the 2-bit binary address lines, A0 and A1. An
EN input on both devices is used to enable or disable the device.
When disabled, all channels are switched off.
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. Inherent
in the design is low charge injection for minimum transients
when switching the digital inputs.

The low on resistance of these switches make them ideal solu-
tions for data acquisition and gain switching applications where
low on resistance and distortion is critical. The on-resistance
profile is very flat over the full analog input range, ensuring
excellent linearity and low distortion when switching audio
signals.
CMOS construction ensures ultralow power dissipation,
making the parts ideally suited for portable and battery-
powered instruments.
