## Overview

The HiLetgo DDS AD9850 Signal Generator Module delivers professional-grade 0-40MHz sine and square wave outputs with enhanced signal purity via a 70MHz low-pass filter. Compact and Arduino-compatible, it’s engineered for flexible, precise waveform generation, making it an essential tool for engineers and makers demanding reliable IC test equipment.

## Description

Features:Generate the DA reference pin (PIN12) leads to facilitate the application of the output waveform amplitude adjustment.Comparator reference input voltage generated by the variable resistor, adjust the resistance can be different duty cycle square waveSpecification:Model: AD9850. Color:as shown in the pictures. Material: durable PCB board and metal. Dimension (L*W): about 4.5cm x 2.6cm. Package Included: 1 * DDS AD9850 Signal Generator Module

Review: Many of these modules available on the Internet are duds but this one was perfect. It works within specifications and the quality was just fine.
Review: This review is for AD9850 Signal Generator Module board. This board uses AD9850 and it is capable to produce 0-40Mz Sine and Square wave. In order to program the output frequency, one of the ways is to use Arduino. Since this board can handle both 5v and 3.3v, it can work with either UNO/NANO, due or other Arduino boards. The Arduino library can also be found online easily. For me I end up using an Arduino UNO with a prototype shield as this module is breadboard friendly. One friendly reminder of this board, it can generate square wave with 5v amplitude. For sine wave, it can only generate around 1v peak to peak voltage. Also make sure you adjust the POT for the duty cycle for the square wave. I made a mistake initially and I didn't get any square wave output due to my pot was set to 0% duty cycle. Note that the POT has no effect on the sine wave output. Since I have no problem program the frequency as the board claims, I would recommend this board.

## Features

- AD9850 adopts 125MHz active crystal.
- Can output 2 sine waves and 2 square waves.
- AD9850 frequency range: 0-40MHz. Square Wave: 0-1MHz.
- Using 70MHz low-pass filter to make the waveform of the SN ratio better
- The after harmonic becomes bigger and bigger when the frequency is between 20-30MHz,and the wave form becomes unclean.

*by M***. on 29 May 2017*

I am perplexed about this board. It is fully functional and I was able to easily program and use it. There is documentation for this specific module online (search "eimodule ad9850") and tons of sample code. The output is ok, but not as clean as promised by the Analog Devices simulation software. Where I am really confused is the price. The chip itself sells for at least $14 from Analog Devices (and twice as much fron electronic relailers like Digikey). Counting the PCB, the probably expensive 125MHz oscillator, and the other passive components, I hardly see how it can sell for less than $14, prompting me to think that the 9850 IC could be counterfeit and not representative of the actual product... Regardless, this is a great little board for the price.
