Evaluates: MAX115/MAX116 19-2404 Rev 0 6/01 MAX115 Evaluation Kit General Description Features The MAX115 evaluation system (EV system) is a com- Proven PC Board Layout plete, eight channel data-acquisition system consisting Complete Evaluation System Samples to 40ksps of a MAX115 evaluation kit (EV kit) and a Maxim 68HC16MOD-16WIDE microcontroller (C) module. The Convenient Test Points Provided On-Board MAX115 is a high speed, multichannel, 12-bit data Data-Logging Software with FFT Capability acquisition system with simultaneous track/holds. Windows 3.1/Windows 95 software provides a handy Fully Assembled and Tested user interface to exercise the MAX115s features. Order the complete EV System (MAX115EVB16) for comprehensive evaluation of the MAX115 using a per- sonal computer. Order the EV kit (MAX115EVKIT) if the 68HC16MOD-16WIDE Module has already been pur- chased with a previous Maxim EV system or for custom use in other C-based systems.
