GENERAL DESCRIPTION
The ADG728 and ADG729 are CMOS analog matrix switches
with a serially controlled 2-wire interface. The ADG728 is an
8-channel matrix switch, while the ADG729 is a dual 4-channel
matrix switch. On resistance is closely matched between switches
and very flat over the full signal range. These parts can operate
equally well as either multiplexers, demultiplexers or switch
arrays and the input signal range extends to the supplies.
The ADG728 and ADG729 utilize a 2-wire serial interface that
is compatible with the I
2
C interface standard. Both have two
external address pins (A0 and A1). This allows the 2 LSBs of
the 7-bit slave address to be set by the user. Four of each of the
devices can be connected to the one bus. The ADG728 also has
a
RESET
pin that should be tied high if not in use.
Each channel is controlled by one bit of an 8-bit word. This
means that these devices may be used in a number of different
configurations; all, any, or none of the channels may be on at
any one time.
On power-up of the device, all switches will be in the OFF con-
dition and the internal shift register will contain all zeros.
All channels exhibit break-before-make switching action pre-
venting momentary shorting when switching channels.
The ADG728 and ADG729 are available in 16-lead TSSOP
packages.
PRODUCT HIGHLIGHTS
