DMX512A is one chip with PWM, signal analysis and driving function, the data format follows the DMX512(1990) agreement. This chip is specially designed for LED lighting and decoration use. There are 3 channels output in one chip, each channel carry out 8 bits regulable linearity electric current. This chip are built in with clock circuit, decode module, buffer storage, 3 channels constant flow driver (the electric current can be controlled by the resistance set outside) together with the Oscillator who make the PWM works. The data output port use the special driving design which support the long distance application. The Unique” the output polarity reverse function” enables DMX512A to load additional driving electric circuit; to increase the LED loading and even popularize to the high power LED application。
