GENERAL DESCRIPTION PRODUCT HIGHLIGHTS
The ADG508A and ADG509A are CMOS monolithic analog
multiplexers with eight channels and dual four channels, respectively. The ADG508A switches one of eight inputs to a common
output, depending on the state of three binary addresses and an
enable input. The ADG509A switches one of four differential
inputs to a common differential output, depending on the state
of two binary addresses and an enable input. Both devices have
TTL and 5 V CMOS logic-compatible digital inputs.
The ADG508A and ADG509A are designed on an enhanced
2
MOS process that gives an increased signal capability of VSS
LC
to V
and enables operation over a wide range of supply voltages.
DD
The devices can comfortably operate anywhere in the 10.8 V to
16.5 V single- or dual-supply range. These multiplexers also
feature high switching speeds and low R
ON
.
1. Single-/Dual-Supply Specifications with a Wide Tolerance.
The devices are specified in the 10.8 V to 16.5 V range for
both single and dual supplies.
2. Extended Signal Range. The enhanced LC
results in a high breakdown and an increased analog signal
range of V
to VDD.
SS
3. Break-Before-Make Switching. Switches are guaranteed
reak-before-make so that input signals are protected
b
against momentary shorting.
4. Low Leakage. Leakage currents in the range of 20 pA make
hese multiplexers suitable for high precision circuits.

SINGLE-SUPPLY OCTAL DAC APPLICATION
The following circuit shows the ADG508A connected as a demultiplexer to provide eight separate, digitally programmable voltages
(0 V to 10 V) from the AD7245A. The AD7245A is a complete
12-bit, voltage output DAC with output amplifier and Zener
voltage reference on a monolithic CMOS chip.
The entire system operates from a single 15 V power supply.
The ADG508A is ideally suited for the application because it
has both low charge injection and I
15
(OFF) leakage current.
