AD8381 is a LCD panel driver from Analog Devices. It supports 100Ms/s fast update rate, 10-bit input word rate, output overload protection, power supply voltage range of 9V to 18V.
The AD8381 is a fast, 10‑bit latched decimating digital input device that drives six high‑voltage outputs for LCD panels. It features high‑voltage drive, low power dissipation, standby mode, and flexible logic options such as video inversion and brightness control. The device can be used in parallel configurations to achieve higher resolution displays.
The datasheet provides full electrical specifications, absolute maximum ratings, pin descriptions, timing diagrams, typical performance curves, and ordering information. It also includes package dimensions for the 48‑lead LQFP version and notes on ESD sensitivity and overload protection.
| Supply Voltage Range (DVCC) | 3 V to 5.5 V |
|---|---|
| Operating Temperature Range | 0 °C to 85 °C |
| Output Current per Channel | 30 – 75 mA |
| Resolution | 10 bits |
| Input Data Update Rate | 100 Ms/s |
| Typical Power Dissipation | 570 mW |
The maximum current at any one output of the AD8381 is internally limited to 100 mA average.
When the STBY pin is high, the AVCC current drops to about 1.8 mA.
The AD8381 is offered in a 48‑lead LQFP package measuring 7 mm × 7 mm × 1.4 mm.
The AD8381 dissipates 570 mW of nominal static power.
