DDS Signal Generator AD9850 Module with Dual Output Sine and Square Waves Adjustable Amplitude

DDS Signal Generator AD9850 Module with Dual Output Sine and Square Waves Adjustable Amplitude Description

Key benefits Improved waveform quality: A 70 MHz lowpass filter enhances the signaltonoise ratio of the waveform, reducing frequency content that can affect measurement accuracy. Easy amplitude adjustment via accessible pin: The pin that generates the DA reference is accessible for convenient adjustment of the output waveform amplitude to suit your specific application. Flexible square wave duty cycle: The duty cycle of the square wave output can be adjusted by changing the variable resistor, allowing different timing characteristics for your circuits. Stable and accurate oscillators: The AD9850 module uses a 125 MHz active oscillator, while the AD9851 module uses a 30 MHz active oscillator, providing reliable and predictable frequency generation. Flexible data input: The design allows selection between parallel and serial data input to fit your control interface and project needs. Compact form factor: Dimension is 4.5 cm x 2.6 cm, suitable for compact test setups and crowded boards.
