GENERAL DESCRIPTION

The ADG726/ADG732 are monolithic CMOS 32

channel/dual 16 channel analog multiplexers. The

ADG732 switches one of thirty-two inputs (S1-S32) to a

common output, D, as determined by the 5-bit binary

address lines A0, A1, A2, A3 and A4. The ADG726

switches one of sixteen inputs as determined by the four

bit binary address lines, A0, A1, A2 and A3.

On chip latches facilitate microprocessor interfacing. The

ADG726 device may also be configured for differential

operation by tying CSA and CSB together. An

EN input

is used to enable or disable the devices. When disabled, all

channels are switched OFF.

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

supplies are blocked. All channels exhibit break before

make switching action preventing momentary shorting

when switching channels.
