PART IC PACKAGE INTERFACE TYPE MAX1168EVKIT 24 QSOP User-supplied MAX1168EVC16 24 QSOP Windows software Note: The MAX1168 software is included with the MAX1168 EV kit, but is designed for use with the complete EV system. The EV system includes a C module, USBT0232, and the EV kit. If the Windows software is not required, the EV kit board can be pur- chased by itself, without the C module. Note: To evaluate the MAX1068, request a free sample of the MAX1068 CEG when ordering the MAX1168 EV kit.
