DS3994Z+

Overview

The DS3994Z+ is a four-channel cold-cathode fluorescent lamp (CCFL) controller manufactured by Analog Devices Inc./Maxim Integrated. It functions as a display driver and controller designed for managing CCFL backlights in liquid crystal displays. The device integrates the necessary circuitry to generate high-voltage AC drive signals required to illuminate CCFL tubes efficiently.

Feature Summary

Provides integrated control logic for four independent CCFL channels
Generates high-frequency AC drive signals suitable for cold-cathode fluorescent lamps
Designed specifically for display backlighting applications requiring precise channel management

Applications

Liquid crystal display (LCD) backlight systems
Cold-cathode fluorescent lamp driver circuits
Display controller modules for industrial or consumer electronics

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinued status. Confirm RoHS compliance markings on physical units. Validate package integrity against shipping damage risks associated with older inventory sources. Cross-reference datasheet revisions to ensure functional compatibility with existing system designs.

Selection Notes

Select this component only when designing systems requiring dedicated four-channel CCFL control. Evaluate pinout compatibility with existing PCB layouts if replacing earlier versions. Consider power supply requirements and thermal dissipation capabilities inherent to the SOIC-28 package configuration during integration planning.

Part Context

This part belongs to the Maxim Integrated display driver portfolio, now under Analog Devices Inc. following acquisition. It serves as a specialized controller within the broader category of display interface solutions, targeting legacy LCD technologies utilizing CCFL illumination rather than modern LED-based backlights.
