AD9744ACP-PCB屬于開發(fā)板套件編程器的評估板-數(shù)模轉換器（DAC）。由亞德諾半導體技術有限公司制造生產(chǎn)的AD9744ACP-PCB評估板 - 數(shù)模轉換器（DAC）該系列產(chǎn)品提供了一種方便的方法，在經(jīng)過驗證的設計環(huán)境中對用于將數(shù)字數(shù)據(jù)轉換為模擬格式的器件進行性能或特性評估。重點器件涵蓋范圍從以適合學生或愛好者使用的方式實現(xiàn)的適度功能器件，到適合電信基礎設施應用的高級器件。

GENERAL DESCRIPTION

The AD9744 is a 14-bit resolution, wideband, third generation member of the TxDAC series of high performance, low power CMOS digital-to-analog converters (DACs). The TxDAC family,

consisting of pin-compatible 8-, 10-, 12-, and 14-bit DACs, is specifically optimized for the transmit signal path of communication systems. All of the devices share the same interface options, small outline package, and pinout, providing an upward or downward component selection path based on performance, resolution, and cost. The AD9744 offers exceptional ac and dc performance while supporting update rates up to 210 MSPS.
