GENERAL DESCRIPTION
The ADG725/ADG731 are monolithic CMOS 32
channel/dual 16 channel analog multiplexers with a
serially controlled 3-wire interface. The ADG732 switches
one of thirty-two inputs (S1-S32) to a common output, D.
The ADG725 can be configured as a dual mux switching
one of sixteen inputs to one output or a differential mux
switching one of sixteen inputs to a differential output.
These mulitplexers utilize a 3-wire serial interface that is
compatible with SPI
TM
, QSPI
TM
, MICROWIRE
TM
and
some DSP interface standards. On power-up, the internal
shift register contains all zeros and all switch are in the
OFF state.
These multiplexers are designed on an enhanced submi-
cron process that provides low power dissipation yet gives
high switching speed, very low on resistance and leakage
currents. They operate from single supply of 1.8V to 5.5V
and ±2.5 V dual supply, making them ideally suited to a
variety of applications. On resistance is in the region of a
few Ohms and is closely matched between switches and
very flat over the full signal range. These parts can operate
equally well as either Multiplexers or De-Multiplexers
PRODUCT HIGHLIGHTS

and have an input signal range which extends to the sup-
plies. 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.
They are available in either 48 lead CSP or TQFP
package.
