GENERAL DESCRIPTION  
PRODUCT HIGHLIGHTS  
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 LC2MOS processing  
results in a high breakdown and an increased analog signal  
The ADG508A and ADG509A are CMOS monolithic analog  
multiplexers with eight channels and dual four channels, respec-  
tively. 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.  
range of VSS to VDD  
.
3. Break-Before-Make Switching. Switches are guaranteed  
break-before-make so that input signals are protected  
against momentary shorting.  
The ADG508A and ADG509A are designed on an enhanced  
LC2MOS process that gives an increased signal capability of VSS  
to VDD and enables operation over a wide range of supply voltages.  
The devices can comfortably operate anywhere in the 10.8 V to  
16.5 V single- or dual-supply range. These multiplexers also  
4. Low Leakage. Leakage currents in the range of 20 pA make  
these multiplexers suitable for high precision circuits.  
feature high switching speeds and low RON

SINGLE-SUPPLY OCTAL DAC APPLICATION  
The following circuit shows the ADG508A connected as a demulti-  
plexer 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 IS (OFF) leakage current.
