AD9832BRU

AD9832BRU Description

The AD9832BRU from Analog Devices Inc. is a 10-bit resolution Direct Digital Synthesis (DDS) IC designed for high-precision frequency generation. Operating with a master clock (fclk) of 25 MHz and a 32-bit tuning word width, it delivers exceptional frequency agility and fine-tuning resolution. The device supports a wide supply voltage range (2.97V to 5.5V), making it versatile for both low-power and standard industrial applications. Packaged in a 16-pin TSSOP and classified under ECCN EAR99, it is suitable for surface-mount designs. Though marked as obsolete, its performance remains relevant in legacy and specialized systems.
