ADI’s AD9833 is a programmable waveform generator producing triangular, square, and sine wave outputs which is ideal for sensing, actuation, and time domain reflectometry applications. Both the frequency and phase are programmable with 3-wire serial peripheral interface (SPI). This generator requires no external components to operate which reduces board space and cost. The AD9833 comes in an MSOP-10 package and it has various operational temperature range options available, up to -55°C to +125°C. The AD9833 is perfect for test and medical equipment where sensing applications of proximity, motion, and defect detection is needed.
