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 I
