INTRODUCTION
The DS2740K evaluation kit makes performance evaluation, software development, and prototyping with
the DS2740 high-precision coulomb counting IC easy. The evaluation board interfaces to a PC running
Windows 95 or newer through a DS9123 serial port adapter and RJ-11 cable connection. The CD-ROM
provided contains all related data sheets along with the evaluation software.
The DS2740K evaluation software gives the user complete control of all functions of the DS2740.
Separate control tabs allow the user access to all memory locations, all status registers, and real-time
updates of all monitored parameters. The software also incorporates a data-logging feature to monitor a
battery over time.
The evaluation board circuit is designed to provide the DS2740 with accurate parameter measurements
and protect the DS2740 from ESD damage.
*Kit demonstration boards will vary as they are improved upon over time. For information on the
demonstration board circuits refer to the documentation directory on the DS2740K CD-ROM.
