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.
