Краткое описание:
Audio Synchronized Color LED Driver with I2C Interface
Дополнительная информация
The LM4970 is a LED driver featuring an audio synchronization mode that automatically filters input audio into three frequency bands, each assigned to a specific PWM LED driver. It includes three individual PWM color LED drivers providing up to 42mA of current drive each, eliminating the need for external current limiting resistors. The device is programmable via an I2C compatible interface for custom patterns, color, and intensity.
