MAX6974 Evaluation Kit
General Description
The MAX6974 evaluation kit (EV kit) is an assembled and
tested printed circuit board (PCB) that demonstrates the
MAX6974/ MAX6975 precision current-sinking, 24-output
PWM LED drivers. The MAX6974/MAX6975 functionality
can be evaluated using the MAX6974 EV kit. The
MAX6975 has 14-bit individual PWM and 5-bit global
PWM, while the MAX6974 has 12-bit individual PWM and
7-bit global PWM. The evaluation kit comes with a
MAX6974ATL+ installed. The Windows® 98/2000/XP
software supports only the MAX6974.
