Excellent Sine Source
A very good little circuit. It is cheaper to buy this than a single AD9833 IC. I've tested it from 30mV to 3.5V sine wave. My requirement is 125kHz, but be aware that higher frequencies will start to loose gain because of the Gain Bandwidth Product. If you do need higher frequencies, you could likely swap out a pin compatible opamps with a higher GBWP. The AD9833 has an Arduino Library which is useful for quickly getting it going. For my application, this is a big step towards replacing an expensive signal generator.

Ok but not so good at the higher frequencies

La scheda funziona molto bene, ho ordinato una seconda su cui vorrei fare alcune modifiche. In precedenza ho provato una scheda semplice solo con AD9833 ma probabilmente per causa del oscillatore a cristallo di qualità inferiore, ogni tanto la frequenza generata non era giusta.

Mein Modul hat auf Anhieb einwandfrei funktioniert. Beachte: Man braucht 2 SPI-Kanäle für "Fsync" (Frequenzeinstellung) und "CS" (Pegeleinstellung). Schade daß die Arduino Library "MCP_POT" für die Pegeleinstellung zwei Pins zusätzlich blockiert, die unbenutzt sind. Aber es gibt ja auch andere Libraries, die ich jedoch nicht getestet habe ...

Je dispose d'un oscilloscope et du matériel nécessaire à la programmation de ce module, cependant il ne fonctionne pas après de nombreuses heures. La sortie de l'AD9833 est incorrecte, l'écriture des registres ne fonctionne pas malgré l'utilisation de 4 dispositifs différents disposant d'une liaison SPI. A fuir.

Fonctionne comme prévu, avec l'utilisation de code Arduino trouvé sur internet. Pas de différence notable au niveau des performances si on compare avec d'autres cartes utilisant moins de composants externes pour la même IC. Il serait intéressant de savoir pourquoi...
