GENERAL DESCRIPTION
The AD9834 is a 50 MHz low power DDS device capable of
producing high performance sine and triangular outputs. It also
has an on-board comparator that allows a square wave to be
produced for clock generation. Consuming only 20 mW of
power at 3 V makes the AD9834 an ideal candidate for po
