AD7898AR-3REEL7集成電路（IC）的模數(shù)轉換器（ADC）規(guī)格書PDF中文資料

AD7898AR-3REEL7屬于集成電路（IC）的模數(shù)轉換器（ADC）。由亞德諾半導體技術有限公司制造生產(chǎn)的AD7898AR-3REEL7模數(shù)轉換器（ADC）模數(shù)轉換器（ADC、A/D 或 A 轉 D）對模擬信號進行采樣，例如由麥克風采集的聲音或傳感器的輸出，然后將其轉換為數(shù)字信號。一般來說，數(shù)字輸出是二進制補碼二進制數(shù)，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數(shù)轉換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉換器數(shù)和架構（例如自適應增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進行選擇。

GENERAL DESCRIPTION

The AD7898 is a fast 12-bit ADC that operates from a single 5 V supply and is housed in a small 8-lead SOIC package. The part contains a successive approximation A/D converter, an on-chip track/hold amplifier, an on-chip clock, and a high speed serial interface.
