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.
