隔離式Σ-Δ調制器

AD7401*是一款二階Σ-Δ調制器，采用ADI公司iCoupler?技術的片內數字隔離，能將模擬輸入信號轉換為高速的1比特的數據流。AD7401采用5V電源供電，可輸入±200 mV的差分信號（滿量程±320 mV）。模擬調制器對模擬輸入信號連續(xù)采樣，因而無需外部采樣保持電路。輸入信息包含在數據率最高為20 MHz的輸出流中，通過適當的數字濾波器可重構原始信息。串行I/O可采用5 V或3 V電源供電(VDD2)。\n\n 串行接口采用數字式隔離。通過將高速CMOS工藝和單片空芯變壓器技術結合在一起，較之傳統(tǒng)光耦合器等其它元件來說，片內隔離能提供更加優(yōu)異的工作特性。該器件內置片內基準 ? 20 MHz 最大外部時鐘速率\n\n? 二階調制器\n\n? 16位無失碼\n\n? 16位時INL典型值為±2 LSB\n\n? 最大失調漂移為3.5 μV/°C \n\n? 片內數字隔離器 \n\n? 片內基準電壓源;
