GENERAL DESCRIPTION

The ADG786 and ADG788 are low voltage, CMOS devices

comprising three independently selectable SPDT (single pole,

double throw) switches and four independently selectable SPDT

switches respectively.

Low power consumption and operating supply range of 1.8 V to

5.5 V and dual

±2.5 V make the ADG786 and ADG788 ideal

for battery powered, portable instruments and many other

applications. All channels exhibit break-before-make switch-

ing action preventing momentary shorting when switching

channels. An

EN input on the ADG786 is used to enable or

disable the device. When disabled, all channels are switched OFF.

These multiplexers are designed on an enhanced submicron

process that provides low power dissipation yet gives high switch-

ing speed, very low on resistance, high signal bandwidths and

low leakage currents. On resistance is in the region of a few

ohms, is closely matched between switches and very flat over

the full signal range. These parts can operate equally well in

either direction and have an input signal range which extends to

the supplies.

The ADG786 and ADG788 are available in small 20-lead

chip scale packages.

PRODUCT HIGHLIGHTS
