AD9731数据手册ADI中文资料规格书

描述 Description

The AD9731 is a l0-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 AD9731 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 proliferation of digital communications into basestation and high volume subscriber-end markets has created a demand for excellent DAC performance delivered at reduced levels of power dissipation and cost.The AD9731 is the answer to that demand.
