EVAL-AD7944EBZ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EVAL-AD7944EBZ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 AD79441 is a 14-bit, 2.5 MSPS successive approximation analog-to-digital converter (SAR ADC). It contains a low power, high speed, 14-bit sampling ADC, an internal conversion clock, an internal reference (and buffer), error correction circuits, and a versatile serial interface port. On the rising edge of CNV, the AD7944 samples an analog input, IN+, between 0 V and VREF with respect to a ground sense, IN?. The AD7944 features a very high sampling rate turbo mode (TURBO high) and a reduced power normal mode (TURBO low) for low power applications where the power is scaled with the throughput.
