GENERAL DESCRIPTION
The ADG708/ADG709 are low voltage, CMOS analog
multiplexers comprising eight single channels and four
differential channels, respectively. The ADG708 switches one of
eight inputs (S1 to S8) to a common output, D, as determined
by the 3-bit binary address lines A0, A1, and A2. The ADG709
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 ADG708/ADG709 ideal for battery-
powered, portable instruments. All channels exhibit break-
before-make switching action preventing momentary shorting
when switching 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 ADG708/ADG709 are available in a 16-lead TSSOP.
