Projects & KitsElectronics Assembled PCB / Breakout BoardsAD9835 Signal Generator Breakout Board
This is a breakout board from Sparkfun BOB-09169 for the AD9835 signal generator chip from Analog devices. The AD9835 allows the user to make sine waves from 1Hz up to 25MHz with better than 1Hz resolution.
The breakout board has digital and analog supplies with separated ground planes, plus an SMA connector and 2-pin 0.1"-spaced header available for RF output. The output impedance is somewhat high (you can't drive a speaker), so you may want to buffer the signal with an op amp.
Features:
* 10-bit DAC for good accuracy
* 2 frequency registers, plus a register-select
* 4 phase registers, plus 2 register select pins
* SPI communication with a simple command set
* Input voltage 6-9V
* Current consumption 5 to 40mA
* 5V SPI interface
Dimensions: 31 x 25 mm
Weight: 4.3 grams
