GENERAL DESCRIPTION
The ADG406, ADG407 and ADG426 are monolithic CMOS
analog multiplexers. The ADG406 and ADG426 switch one of
sixteen inputs to a common output as determined by the 4-bit
binary address lines A0, A1, A2 and A3. The ADG426 has on-
chip address and control latches that facilitate microprocessor
interfacing. The ADG407 switches one of eight differential
inputs to a common differential output as determined by the 3-
bit binary address lines A0, A1 and A2. An EN input on all
devices is used to enable or disable the device. When disabled,
all channels are switched OFF.
The ADG406/ADG407/ADG426 are designed on an enhanced
LC
high switching speed and low on resistance. These features
make the parts suitable for high speed data acquisition systems
and audio signal switching. Low power dissipation makes the
parts suitable for battery powered systems. Each channel
conducts equally well in both directions when ON and has an
input signal range which extends to the supplies. In the OFF
condition, signal levels up to the supplies are blocked. All
channels exhibit break before make switching action preventing
momentary shorting when switching channels. Inherent in the
design is low charge injection for minimum transients when
switching the digital inputs.

The ADG406/ADG407/ADG426 are fabricated on an
enhanced LC
which extends to the supply rails
For applications where the analog signal is unipolar, the
ADG406/ADG407/ADG426 can be operated from a single
rail power supply. The parts are fully specified with a single
+12 V power supply and will remain functional with single
supplies as low as +5 V.
