AD674B集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

AD674B屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的AD674B模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) 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(zhuǎn)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(zhuǎn)換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉(zhuǎn)換器數(shù)和架構(gòu)（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。

PRODUCT DESCRIPTION

The AD674B and AD774B are complete 12-bit successive approximation analog-to-digital converters with three-state output buffer circuitry for direct interface to 8- and 16-bit microprocessor busses. A high-precision voltage reference and clock are included on chip, and the circuit requires only power supplies and control signals for operation. The AD674B and AD774B are pin-compatible with the industry standard AD574A, but offer faster conversion time and bus access speed than the AD574A and lower power consumption. The AD674B converts in 15 μs (maximum) and the AD774B converts in 8 μs (maximum).
