采用LVDS接口的16位隔离式Σ-Δ调制器

AD7405是一款高性能二阶Σ-Δ调制器，片上的数字隔离采用ADI公司的iCoupler®技术，能将模拟输入信号转换为高速单个位LVDS数据流。 AD7405采用5 V (VDD1)电源供电，可输入±250 mV的差分信号（满量程±320 mV）。 该差分输入信号非常适合用于在要求电流隔离的高电压应用中监控分流电压。 \n\n 模拟输入由高性能模拟调制器连续采样，并转换为数据率最高为20 MHz且密度为1的数字输出流。 通过适当的数字滤波器可重构原始信息，以在78.1 kSPS时实现88 dB的信噪比(SNR)。 LVDS输入/输出可采用5 V或3.3 V电源供电(VDD2)。 \n • 外部时钟输入速率：5 MHz至20 MHz \n\n• 16位无失码 \n\n• 信噪比(SNR)： 88 dB（典型值） \n\n• 有效位数(ENOB)： 14.2位（典型值） \n\n• 典型失调温漂： 1.6 μV/℃典型值 \n\n• LVDS接口;
