AD9834 is a 75 MHz, low power DDS device that can generate high-performance sine wave and triangle wave outputs. Its features include narrowband SFDR > 72 dB, power supply range of 2.3 V to 5.5 V, output frequency up to 37.5 MHz, on-board comparator, power-saving options, etc.
The AD9834 is a 75 MHz, low-power Direct Digital Synthesis (DDS) device that generates high-performance sine and triangle wave outputs. It features an on-chip comparator to generate square waves for clock generation. With a power consumption of only 20 mW at 3 V, it is ideal for applications with strict power requirements. The device supports phase and frequency modulation and features a 28-bit frequency register for high-precision frequency control. This manual is written in Chinese.
