Hello!
So, your project requires a breakout board for the AD5933 impedance analyzer, targeting measurements up to 100 kHz via I2C.
(you're highly welcome to visit my profile for related project examples)
My approach:
Datasheet Analysis: Thorough review of the AD5933 datasheet to understand its specifications, operating modes, and interface requirements, including frequency range, excitation settings, and I2C protocol.
Optimized Circuit Design: Design a circuit with the AD5933, I2C interface (with pull-ups and level shifting if needed), stable external clock, precise feedback resistor (R<sub>FB</sub>), Kelvin connections for Z<sub>UNK</sub> (if required), and effective power supply filtering.
High-Performance PCB Layout: Optimize the layout to minimize parasitic effects, using a solid ground plane and strategic component placement for accurate measurements, especially at higher frequencies.
I2C Implementation Guidance: Provide example code or guidance for I2C communication with the AD5933.
Comprehensive Deliverables: Deliver schematic (PDF and editable format), Gerber files, BOM, and basic test procedures.
My expertise in analog circuit design, PCB layout, microcontroller interfacing, and impedance measurement principles ensures a high-quality AD5933 breakout board meeting your specifications.
