Evaluates: MAX11300 MAX11300 Evaluation Kit General Description Quick Start The MAX11300 evaluation kit (EV kit) provides a proven Required Equipment design to evaluate the MAX11300 20-port program- EV kit (USB mini-B cable included) mable mixed-signal I/O with 12-bit ADC, 12-bit DAC, Windows XP, Windows Vista, Windows 7, Windows analog switches, and GPIO. The EV kit also includes 8.0, or Windows 8.1 PC, running .NET v4, with a Windows XP -, Windows Vista -, Windows 7-, and spare USB port Windows 8.0-/8.1-compatible software that provides a simple graphical user interface (GUI) for exercising the 12.5V DC at 500mA dual-output DC power supply features of the IC. Digital voltmeter (DVM) The EV kit comes with a MAX11300GTL+ installed. Note: In the following sections, software-related items are identified by bolding.
