General Description

The AS1122 is a 12-channel, constant current-sink LED driver.

Each of the 12 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 AS1122 channels and other LED drivers.

Key Features
