AL58263 Overview
Key Specifications
Description
The AL58263 is a 16-channel constant-current LED driver with 16-bit grayscale Adaptive Pulse Density Modulation (APDM) and supports error diagnostics, power-saving functionality, and current gain control. This distinctive APDM technology abates the non-ideal IOUT distortion due to non-symmetric transient responses and enhances the refresh rate by efficiently separating the frame waveform.
