AD7701集成電路（IC）的模數(shù)轉換器（ADC）規(guī)格書PDF中文資料

AD7701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AD7701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 AD7701 is a 16-bit ADC that uses a sigma-delta conversion technique. The analog input is continuously sampled by an analog modulator whose mean output duty cycle is proportional to the input signal. The modulator output is processed by an on-chip digital filter with a six-pole Gaussian response, which updates the output data register with 16-bit binary words at word rates up to 4 kHz. The sampling rate, filter corner frequency, and output word rate are set by a master clock input that may be supplied externally, or by a crystal controlled on-chip clock oscillator.
