IS31FL3732A AUDIO MODULATED MATRIX LED DRIVER

The IS31FL3732A is a compact LED driver for 144 single LEDs. The device can be programmed via an I2C compatible interface. The IS31FL3732A offers two blocks each driving 72 LEDs with 1/9 cycle rate. The required lines to drive all 144 LEDs are reduced to 18 by using the cross-plexing feature optimizing space on the PCB. Additionally each of the 144 LEDs can .
