This document describes the features and characteristics of the high-performance, 12-bit, 12-channel decimating LCD DecDriver® AD8387 product.
The AD8387 is a high‑performance, 12‑bit, 12‑channel LCD DecDriver that delivers fast, high‑voltage video outputs. It features laser‑trimmed DACs, programmable video reference and contrast levels, and flexible logic for signal inversion and data bus configuration. The device operates from 3.3 V digital and 11‑18 V analog supplies and dissipates 1.34 W nominal static power.
The document includes a functional block diagram, detailed pin configuration, absolute maximum ratings, overload protection mechanisms, thermal pad and via design recommendations, and typical performance curves such as settling time, slew rate, and channel matching versus temperature and code. It also provides ordering information for the 80‑lead TQFP package.
| Resolution | 12 bits |
|---|---|
| Output current per channel | 100 mA |
| AVCC supply range | 11 V to 18 V |
| DVCC supply range | 3 V to 3.6 V |
| Settling time (0.25 % into 150 pF) | 35 ns |
| Slew rate | 420 V/µs |
| Static power dissipation | 1.34 W |
| Maximum power dissipation (TQFP E‑Pad) | 4.38 W @ 25 °C |
Each output is limited to an average of 100 mA by the internal current limiter.
AVCC should be between 11 V and 18 V.
It uses an output current limiter together with a thermal switch for overload protection.
