DM621

Application Diagram

Just connected as the architecture illustrated above, DM621 could automatically

produce the global latch and make serial data possible. The system just needs four lines

(VDD, VSS, SIN, and DCK) to realize the cascade architecture. Please utilize a slower

DM621 could be utilized as a PWM

generator. In this case, DM621 will

output inverse PWM signals by the

POLAR command.
