Overview

Features and Benefits

  • Compact, 31.24mm x 12.83mm PCB
  • Impedance measurements from 1 Hz to 1.5 MHz
  • Typical relative accuracy: 0.015% - 0.2%
  • 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)
  • Designed to help meet leakage requirements for IEC 60601-1*
  • 6 display mode formats (R/X, Z/θ (deg), Z/θ (rad), G/B, Y/θ (deg), Y/θ (rad))
  • Command line, Graphical user interface, and Python API for easy system evaluation and data collection
  • USB-C connector provides power and serial communication to 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. The hardware can be modified to limit the current depending on application specifications and voltage drive needs

Product Details

The AD-IMP2501-SL is an impedance analyzer demonstrator and technology evaluation system comprised of both the AD-IMP2501DBZ-SL and the AD-IMP2501EBZ-SL boards.

The AD-IMP2501EBZ-SL is the carrier board that allows for simplified host PC communication interfacing, varying 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 - 2.4V at 1 Hz up to 1.5 MHz, differential voltage measurement, current return measurement, and full impedance processing with a 120 MHz Arm Cortex-M4 microprocessor. All in a sub 400mm square PCB.
