AD9734屬于開發(fā)板套件編程器的評(píng)估板-數(shù)模轉(zhuǎn)換器（DAC）。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD9734評(píng)估板 - 數(shù)模轉(zhuǎn)換器（DAC）該系列產(chǎn)品提供了一種方便的方法，在經(jīng)過驗(yàn)證的設(shè)計(jì)環(huán)境中對(duì)用于將數(shù)字?jǐn)?shù)據(jù)轉(zhuǎn)換為模擬格式的器件進(jìn)行性能或特性評(píng)估。重點(diǎn)器件涵蓋范圍從以適合學(xué)生或愛好者使用的方式實(shí)現(xiàn)的適度功能器件，到適合電信基礎(chǔ)設(shè)施應(yīng)用的高級(jí)器件。

GENERAL DESCRIPTION

The AD9736, AD9735, and AD9734 are high performance, high frequency DACs that provide sample rates of up to 1200 MSPS, permitting multicarrier generation up to their Nyquist frequency. The AD9736 is the 14-bit member of the family, while the AD9735 and the AD9734 are the 12-bit and 10-bit members, respectively. They include a serial peripheral interface (SPI) port that provides for programming of many internal parameters and enables readback of status registers.
