3 说明
AMC1306 是一款高精度 Δ-Σ 调制器,通过抗电磁干扰性能极强的电容式双隔离层将输出与输入电路隔离开。该隔离层经过认证,可以按照 DIN VDE V 0884-11 和 UL1577 标准提供高达 7000VPEAK 的增强型隔离。与隔离式电源结合使用时,该隔离式调制器可将以不同共模电压等级运行的系统的各器件隔开,并防止较低电压器件损坏。
AMC1306 的输入针对直接连接分流电阻器或其他低电压等级信号源进行了优化。器件具有独特的 ±50mV 低输入电压范围,可通过分流器显著降低功率耗散,同时具有出色的交流和直流性能。AMC1306 的输出位流采用曼彻斯特编码 (AMC1306Ex) 或未编码 (AMC1306Mx),具体情况因导数而异。通过使用集成式数字滤波器(如 TMS320F2807x 或 TMS320F2837x 微控制器系列中的滤波器)来抽取位流,该器件可在 78kSPS 数据速率下实现 85dB 动态范围的 16 位分辨率。
曼彻斯特编码的 AMC1306Ex 版本的位流输出支持单线数据和时钟传输,无需考虑接收设备的设置和保持时间要求。
