描述 Description

ET6298 is a constant current LED driver circuit with 256 steps linear current control function. Built-in 16 independent low-resistance color LED driver channels, can adjust each channel’s current. Through code selection, each channel can provide four current range: 5mA, 10mA, 20mA, 40mA. ET6298 integrate 7 audio equalizer, subdivide 20Hz~20KHz input audio signal into 7 frequencies by built-in bandpass filters, and through the built-in high resolution ADC converts the average amplitude of each frequency value into corresponding data, control 7 output current channels. In audio synchronization mode, MCU needn’t any data operation, only need to set up the corresponding instruction, LED brightness will change along with the music beats. ET6298 also have half fade function, in this mode, MCU just completed the brightness and darkest time cycle control and send single instruction to set fade direction(fade-in or fade-out), ET6298 will automatically complete fade-in or fade-out cycle control, this will greatly reduce the hardware and software overhead.
