SWITCHES SHOWN FOR A LOGIC “1” INPUT
The ADG786 and ADG788 are low voltage, CMOS devices
comprising three independently selectable SPDT (single pole,
double throw) switches and four independently selectable SPDT
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 ADG786 and ADG788 are available in small 20-lead
chip scale packages.
