AD5934是一款高精度的阻抗转换器系统解决方案,片上集成一个频率发生器和一个12位、250 kSPS模数转换器(ADC)。用频率发生器产生的信号来激励外部复阻抗,外部阻抗的响应信号由片上ADC进行采样,然后由片上DSP进行离散傅里叶变换(DFT)处理。DFT算法在每个频率上返回一个实部(R)数据字和一个虚部(I)数据字。

校准后,使用以下两个公式很容易算出各扫描频率点的阻抗幅度和相应的阻抗相位:

幅度 = √ R2 + I2 相位 = Tan-1 (I/R)

ADI公司还提供一款类似器件AD5933,它是一款2.7 V至5.5 V、1 MSPS、12位阻抗转换器,内置温度传感器,并采用16引脚SSOP封装。
