Product Summary
The AD9731BR is a 10-bit, 170 MSPS, bipolar D/A converter that is optimized to provide high dynamic performance, yet offer lower power dissipation and more economical pricing than afforded by previous bipolar high performance DAC solutions. The AD9731BR was designed primarily for demanding communications systems applications where wideband spurious-free dynamic range (SFDR) requirements are strenuous and could previously only be met by using a high performance DAC such as the industry-standard AD9721.The AD9731BR is widely used in Digital Communications, Direct Digital Synthesis, Waveform Reconstruction, High Speed Imaging and 5 MHz–65 MHz HFC Upstream Path.
