What it drives and how it sits on the board
The AD8382ACP is a 6-segment LCD driver from Analog Devices, designed to drive LCD panels via an analog parallel interface. The part draws 43 mA from the supply chain, which covers the segment drive current and the internal bias generation. That 43 mA is the total supply current — budget it into the system power calculation alongside the LCD panel's own backlight draw.
Housed in a 48-lead LFCSP-WQ (7x7 mm) — that is the 48-WFQFN exposed-pad CSP variant. The exposed pad underneath is the thermal and electrical ground connection; the PCB layout must include a matching thermal land with vias to the ground plane to pull heat out of the die. The 0.5 mm pitch on the perimeter leads means a four-layer board with a solid ground pour under the package is the safe bet for signal integrity and thermal management. This fits indoor equipment, bench instruments, and consumer displays, but not an outdoor panel that sees freezing start-up or a hot enclosure above 85 °C.
