AS1122 driver equivalent, 12-channel led driver.
Greyscale PWM Control: 12-Bit (4096 Steps) Dot Correction: 6-Bit (64 Steps) Drive Capability (Constant-Current Sink): 0 to 40mA LED Power Supply Voltage: up to 30V Supply.
The device is ideal for mono-, multi-, and full-color LED displays, LED signboards, and display backlights.
Figure 1. A.
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 .
