The AD5933 is a single-chip system-level solution for impedance conversion. It includes internal clock, data acquisition, data storage, and digital communication functions, making it an ideal choice for portable, compact impedance converters.
The AD5933 provides a single-chip system-level solution for impedance conversion, combining an on-board frequency generator and a 12-bit, 1 MSPS ADC. It includes integrated Fourier processing to measure impedance by extracting real and imaginary components of the response signal at each frequency point. This integrated solution delivers precision and accuracy in a compact 16-lead SSOP package, requiring less design time and power compared to discrete solutions.
