Mikroe Waveform 3 Click represents a high-performance signal generator and features the Analog Devices AD9837. The AD9837 is a low-power programmable waveform generator capable of producing sine, triangular, and square wave outputs. This direct digital synthesizer creates arbitrary analog waveforms from a fixed-frequency reference clock. It has software programmable output frequency and phase via a 3-wire SPI serial interface and is compatible with DSP standards.
