The AD-IMP2501EBZ-SL is the carrier board that enables simplified host PC communication interfacing, varied electrical load connections, and easier setup/debug.
The AD-IMP2501DBZ-SL is the electrical impedance spectroscopy module, capable of tetrapolar impedance measurements. The module integrates AC waveform signal generation from 0V to 2.4V at 1Hz to 1.5MHz, differential voltage measurement, current return measurement, and full impedance processing with a 120MHz Arm® Cortex®-M4 microprocessor, all in a sub-400mm2 PCB.
It is critical to purchase both the Analog Devices AD-IMP2501DBZ-SL Impedance Analyzer Measurement Module and the AD-IMP2501EBZ-SL Impedance Demonstration Board. Each of these items must be purchased separately by the user.
Features
- Compact, 31.24mm x 12.83mm PCB
- Impedance measurements from 1Hz to 1.5MHz
- 0.015% to 0.2% typical relative accuracy
- Current or Voltage drive excitation modes
- 16-bit acquisition channels
- Operates from a single 5V supply
- UART interface (additional BLE 5.2, USB, and SPI hardware support capable, not implemented)
- Six display mode formats (R/X, Z/θ (deg), Z/θ (rad), G/B, Y/θ (deg), Y/θ (rad))
- Designed to help meet leakage requirements for IEC 60601-1*
- Command line, Graphical user interface, and Python API for easy system evaluation and data collection
- USB Type-C® connector provides power and serial communication to the host PC
- DIN and SMA connectors and for interfacing with an external load
- On board loads with jumper configurations for testing and evaluation without external components or connections
* Current hardware implementation is dependent on voltage drive levels. Engineers can modify the hardware to limit current in accordance with application specifications.
