ADG406/ADG407/ADG426
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
2
MOS process that provides low power dissipation yet gives
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.
