1.2 Kit Contents

This evaluation module contains one PCB evaluation board containing one ISOW3080 device. The major components of the ISOW3080 evaluation board are:

  • ISOW3080DWER isolated RS-485/RS-422 transceiver with integrated power.
  • TPS7A4701RGWR 36V, 1A, 4.17μVRMS, RF Low-Dropout (LDO) Voltage Regulator, RGW0020A (VQFN-20).
  • Multiple test points.

To demonstrate functionality of the ISOW3080DWER, TI recommends the following (not included):

  • 9V or 12V Battery for supply inputs.
  • Signal generator for external dynamic data input.
  • Oscilloscope for probing data channels.
