GENERAL DESCRIPTION

The ADG758 and ADG759 are low voltage, CMOS analog

multiplexers comprising eight single channels and four differential

channels, respectively. The ADG758 switches one of eight inputs

(S1–S8) to a common output, D, as determined by the 3-bit

binary address lines A0, A1, and A2. The ADG759 switches one

of four differential inputs to a common differential output as

determined by the 2-bit binary address lines A0 and A1. An EN

input on both devices is used to enable or disable the device. When

disabled, all channels are switched OFF.

Low power consumption and an operating supply range of 1.8 V to

5.5 V make the ADG758 and ADG759 ideal for battery-powered,

portable instruments. All channels exhibit break-before-make

switching action preventing momentary shorting when switch-

ing channels.

These switches are designed on an enhanced submicron process

that provides low power dissipation yet gives high switching

speed, very low ON resistance and leakage currents. 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 demultiplexers

and have an input signal range that extends to the supplies.

The ADG758 and ADG759 are available in 20-lead chip

scale packages.
