Analog Devices AD8387 12‑Bit 12‑Channel Decimating LCD DecDriver Datasheet
The AD8387 DecDriver provides dual, fast‑latched 12‑bit inputs that drive twelve high‑voltage LCD outputs. It features 12‑bit input resolution, 35 ns settling time into 150 pF loads, 420 V/µs slew rate, and programmable video reference and contrast levels. The device is supplied in an 80‑lead TQFP E‑pad package and operates from 11‑18 V AVCC and 3.3‑3.6 V DVCC.
Designed for LCD micro‑display drivers, the AD8387 includes overload protection via an output current limiter and a thermal switch, and requires careful PCB thermal‑pad and via design. Power‑on/off sequencing and grounded‑output mode procedures are detailed to ensure reliable operation across the 0 °C to 85 °C temperature range.
