GENERAL DESCRIPTION

The AD9833 is a low power, programmable waveform generato capable of producing sine, triangular, and square wave outputs Waveform generation is required in various types of sensing, actuation, and time domain reflectometry (TDR) applications. The output frequency and phase are software programmable, allowing easy tuning. No external components are needed.
