PRELMNARY
DATA
ADG739 is a dual 4 channel matrix switch. On resistance
is closely matched between switches and very flat over the
full signal range.
T he ADG738 and ADG739 utilize a three wire serial
interface that is compatible with SPI
T M
, QSPI
T M
and
MICROWIRE
T M
interface standards. T he output of the
shift register DOUT enables a number of these parts to be
daisy chained. On power up of the devices, the internal
shift register contains all zeros and all switches are in the
OFF state.
Each switch conducts equally well in both direction when
on, making these parts suitable for both multiplexing and
demultiplexing applications. As each switch is turned on
or off by a seperate bit, these parts can also be configured
as a type of switch array, where any, all or none of the 8
switches may be closed at any time. T he input signal
range extends to the supply rails.
