AD7819YR集成電路（IC）的模數轉換器（ADC）規(guī)格書PDF中文資料

AD7819YR屬于集成電路（IC）的模數轉換器（ADC）。由亞德諾半導體技術有限公司制造生產的AD7819YR模數轉換器（ADC）模數轉換器（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，然后將其轉換為數字信號。一般來說，數字輸出是二進制補碼二進制數，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數轉換器可按照位數、采樣率、輸入數、接口、轉換器數和架構（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 AD7819 is a high speed, microprocessor-compatible, 8-bit analog-to-digital converter with a maximum throughput of 200 kSPS. The converter operates off a single 2.7 V to 5.5 V supply and contains a 4.5 μs successive approximation A/D converter, track/hold circuitry, on-chip clock oscillator and 8-bit wide parallel interface. The parallel interface is designed to allow easy interfacing to microprocessors and DSPs. Using only address decoding logic the AD7819 is easily mapped into the microprocessor address space.
