Evaluation Kit/Evaluation System for the MAX1707

Buy Now View Details

Features and Benefits

  • Proven PC Board Layout
  • Windows® 98/2000/XP-Compatible Evaluation Software
  • White LED Camera Flash, RGB Indicator LED, and Four Backlight LEDs
  • Pushbutton for Evaluating Strobe Function
  • Terminals for Access to I²C Interface Lines
  • Fully Assembled and Tested

Product Details

The MAX1707 evaluation system (EV system) includes a MAX1707 evaluation kit (EV kit) and a Maxim command module (CMODUSB).

The MAX1707 EV kit is an assembled and tested PC board that demonstrates the capabilities of the MAX1707 light-management IC. The EV kit includes four main display backlight LEDs, an RGB indicator LED, and a white LED camera flash that can all be driven simultaneously by the MAX1707. The EV kit also includes PC software that allows a user to evaluate every feature of the MAX1707 using a graphical user interface (GUI).

The CMODUSB board connects to a PC's USB port and allows the transfer of I²C commands to the MAX1707 EV kit.

The MAX1707EVKIT can also be used to evaluate the MAX8879.

Applications

  • Cell Phones/Smartphones
  • Displays with Up to 11 LEDs
  • PDAs, Digital Cameras, Camcorders
