CS5571-ISZ集成電路（IC）的模數轉換器（ADC）規(guī)格書PDF中文資料

CS5571-ISZ屬于集成電路（IC）的模數轉換器（ADC）。由凌云邏輯制造生產的CS5571-ISZ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 CS5571 is a single-channel, 16-bit analog-to-digital converter capable of 100 kSps conversion rate. The input accepts a single-ended analog input signal. On-chip buffers provide high input impedance for both the AIN input and the VREF+ input. This significantly reduces the drive requirements of signal sources and reduces errors due to source impedances. The CS5571 is a delta-sigma converter capable of switching multiple input channels at a high rate with no loss in throughput. The ADC uses a low-latency digital filter architecture.
