1.1 Introduction

The ISOW3080DWEEVM user’s guide describes the functionality of the ISOW3080 isolated RS-485/RS-422 transceiver with integrated DC-DC converter. This user’s guide describes EVM operation for ISOW3080 device under VDD1=3.3V and VDDL=3.3V configuration. VISOOUT gets set to 3.3V internally for ISOW3080. However, the EVM can be reconfigured for evaluation of any of the device variants of ISOW308x and ISOW308xP family in a 16-pin WB SOIC package (DWE-16) under the required voltage conditions of that particular variant. See details of each variant in Device Information. This guide also describes the EVM BOM, EVM schematic, EVM PCB layout, and typical laboratory setup.

CAUTION: This evaluation module is made available for isolator parameter performance evaluation only and is not intended for isolation voltage testing. To prevent damage to the EVM, any voltage applied as a supply or digital input/output must be maintained within the recommended operating conditions of the device.
