Require a solution for impedance/Capacitance measurement

Thread Summary

The user is designing a data acquisition system compliant with DO-160, aiming to read data from 32 PZT sensor channels and perform impedance/capacitance measurements. The AD5933 can measure impedance but requires an external ADC and multiplexer for voltage acquisition. The AD5933 LTSpice model is available for system-level simulation.

Hi Team,

We are designing a data acquisition system that shall comply with the DO-160 military standard. In our system, we will be reading the data from the 32x channel PZT sensor as indicated in the block diagram.

In addition to this, we want to perform impedance/capacitance measurements of each PZT sensor channel by using, maybe, a DAC. We have found the AD5933 chip, which could suffice the additional requirements. Please confirm our understanding. Also, please guide us if you have a better part or a discrete solution that is cost-effective.

Thanks & Regards,
Sahil Nayak
