Product Details

The DS2483 evaluation system (EV system) consists of a DS2483 evaluation kit (EV kit) and a DS9400 USB-to-I²C adapter. The DS2483 is an I²C-to-1-Wire® bridge device that performs protocol conversion from an I²C Master to any attached 1-Wire slave devices. Relative to any attached 1-Wire slave device, the DS2483 is a 1-Wire master. The evaluation software runs under a Windows® 7 or Windows XP® operating system (OS), providing a handy user interface to exercise the features of the DS2483.

Order the DS2483K# for the complete EV system to evaluate the DS2483 using a PC. Evaluation software for the EV system is also available on our website at: www.maximintegrated.com/evkit.
