I am using an AD5930 chip to produce a frequency sweep. I am programming the registers through Atmega16 microcontroller. But it seems AD5930 producing a SQUARE wave at the Iout pin of 50Hz frequency not a sinusoidal wave. It is not showing any frequency sweep. Also the IoutB pin is producing the same output as that of Iout pin, its not inverted.
Can someone give me any suggestion what could be the problem?
