10MHz DDS Sine/Square Function Generator AD9835


Posted on Jul 26, 2012

An extremely simple and low cost Sine/Square wave generator based on the Analog Devices AD9835 Direct Digital Synthesis (DDS) Generator chip. The frequency can be set for any frequency from 1Hz to 10MHz in 1Hz resolution steps! All this with three push buttons and a novel `sliding window` LED display.
