GF: SOP24L-300-1.00
- Between ICs: ±3% (typ.) and ±6% (max.)
Visual effect control
Shrink SOP
- Patented S-PWM technology to improve refresh rate
- 16-bit gray scale control
- 6-bit programmable output current gain from 12.5%~200%
Error detections - In-message error detection
GP: SSOP24L-150-0.64
- LED open-circuit detection
- Compulsory error detection: data-independent full panel and silent error detection in 700ns
- Programmable LED short-circuit detection
