Description

The ISO485 evaluation module (EVM) supports the parametric evaluation of RS-485 digital isolators. The EVM will be delivered with an ISO3082DW factory installed on the board. This EVM is intended to be used with the ISO15, ISO35 (SLOS580) and ISO3080, ISO3082, ISO3086 or ISO3088 (SLOS581). If another device is desired, please order samples from www.ti.com. If you do not have the capability to remove and install devices, and would like to have another device factory installed, please contact Technical Support at the link on this page. Note that this EVM is not intended for electromagnetic compatibility (EMC) tests.
