General 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 band audio equalizer, subdivide 20Hz~20KHz input audio signal into 7 frequencies by built-in band-pass 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.
