General Description

The AS1112 is a 16-channel, constant current-sink LEDdriver. Each of the 16 channels can be individually adjusted by 4096-step greyscale PWM brightness control and 64-step constant-current sink (dot correction). The dot correction circuitry adjusts the brightness variations between the AS1112 channels and other LED drivers. Greyscale control and dot correction circuitry are accessible via the SPI-compatible serial interface. A sin
gle external resistor sets the maximum current value of all 16 channels.
