The LM4970 is a LED driver with an audio synchronization
mode that virtually eliminates the need for real time software
processing for LED lighting effects. The LM4970 includes
three individual PWM color LED drivers that provide up to 42-
mA of current drive for each PWM LED output.
The LM4970 features an audio synchronization mode where
the audio input signal that is mixed in from three audio inputs
is filtered into three frequency bands, with each frequency
band assigned to a specific PWM LED driver.
