瑞萨电子数字信号处理（DSP）IC 将来自无刷直流电机和步进电机的旋转变压器传感器的信号转换为 RX MCU 的角度和位置信号。

RAA306400XGFP 是一款 R/D（旋转变压器/数字）转换 IC，用于将旋转变压器检测信号（电气角度信息），即来自单相励磁两相输出型旋转变压器传感器（角度传感器）的基于旋转变压器的机械旋转角度的模拟信号，转换为数字信号，然后输出。

  • 通过高速响应扫描缩短节拍时间，这是其他旋变数字转换器（RDC）IC 无法实现的
  • 支持电压检测和电流检测两种方式，提供绕组误差校正功能，无需限制旋转变压器制造商
  • 提高电机和旋转变压器的可用性
  • 使用常规电机控制 MCU 功能，简化 RDC 电路，以降低设备 (RDC 集成电路) 成本
