The Year of the Waveform Generator. As the prototype was built on the same board with my other experiments, ad835 power supply was not filtered except the decoupling capacitor, output is a bit noisy. The various ranges specified are as follows: This can be one of 4 stages: As you can see, the datashee is not a rocket science either.

Due to environmental concerns, ADI offers many of our products in lead-free versions. At line is a subroutine that calculates a bit frequency word for a frequency given in variable F.

Frequency accuracy can be controlled to one part in 4 billion. If a model is not available for web samples, look for notes on the product page that indicate how to request samples or Contact Ax9835.

Pin Count Pin Count is the number of pins, balls, or pads on the device. Model The model number is a specific dataheet of a generic that can be purchased or sampled. Although the chip is designed for RF applications, it makes a good audio frequency sinewave generator, too.

Temperature Range This is the acceptable operating range of the device. This is the date Analog Devices, Inc. Not to mention a loss of your hard-to-get chip.

This tool also models an estimate of the overall spectral performance, and allows the user to explore the effects of external reconstruction filters. You may want to check out the rfgenerator project for more modern version of the chip, and using it with AVR microcontroller.
