AVT5580 A + - DDS generator for the 1Hz-40MHz range with a wobulator. PCB board and programmed layout

Description

The tunable generators are an important item in the workshop of every constructor. The described generator allows for comfortable work, among others with audio devices, DC / DC converters, microcontrollers or radio communication devices. Its additional advantages are: built-in wobulator function and the possibility of using one of the two types of DDS generator modules with AD9850 chip available on the market. The generator will be useful in the workshop of every constructor electronics.
