AD9248BST-65屬于開發(fā)板套件編程器的評估板-模數(shù)轉(zhuǎn)換器（ADC）。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD9248BST-65評估板 - 模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器 (ADC) 評估板是預(yù)裝有元器件的電路板，用于提供特定 ADC 或器件工作實例。特定板上的 A/D 轉(zhuǎn)換器數(shù)量從 3 到 32 不等，每秒采樣率從 2.5 kHz 到 26 GHz 不等，輸入電壓范圍從 0 到 8 Vp-p。

GENERAL DESCRIPTION

The AD9248 is a dual, 3 V, 14- bit, 20/40/65 MSPS analog - to digital converter. It features dual high performance sample- and hold amplifiers and an integrated vol tage reference. The AD9248 uses a multistage differential pipelined architecture with output error correction logic to provide 14- bit accuracy

and guarantee no missing codes over the full operating temperature range at up to 65 MSPS data rates. The wide bandwidth, differential SHA allows for a variety of user selectable input ranges and offsets including single - ended applications. It is suitable for various applications including multiplexed systems that switch full- scale voltage levels in successive chann els and for sampling inputs at frequencies well

beyond the Nyquist rate.
