ADD8506WWARUZR7

Overview

The ADD8506WWARUZR7 is a six-channel LCD gamma reference buffer designed for line inversion panels. It operates on a single supply voltage ranging from 3.3 V to 6.5 V and supports rail-to-rail input and output capabilities. The device features a wide operating temperature range of −40°C to +105°C and delivers a high output current of 380 mA with a low supply current of 3.9 mA. It maintains stability with capacitive loads up to 1 nF and utilizes a 24-lead thin shrink small outline (TSSOP) package.

Feature Summary

• Six-channel architecture with A/B inputs for selecting between two gamma voltage curves
• High slew rate and output drive capability to ensure reference ladder stability
• Rail-to-rail input and output performance across the full supply voltage range
• Qualified for automotive applications with controlled manufacturing standards

Applications

• LCD line inversion gamma references
• Car navigation panels
• Personal media player panels
• Automotive infotainment systems

Procurement Notes

Verify that the specific part number matches the automotive grade designation, as specifications may differ from commercial models. Confirm the package option corresponds to the required tape and reel format. Ensure compatibility with the target display controller's voltage levels and load requirements before finalizing procurement decisions.

Selection Notes

Select this component when driving column driver gamma inputs in line inversion LCD panels requiring six independent channels. Consider the high output current and slew rate for applications demanding fast response times and stable gray scale performance. Verify that the 24-lead TSSOP footprint fits the design constraints and that the automotive qualification meets system reliability standards.

Part Context

This device belongs to the ADD8504/ADD8505/ADD8506 family of LCD gamma buffers. While the ADD8504 offers four channels and the ADD8505 provides five, the ADD8506 specifically delivers six channels. All variants share similar electrical characteristics and are designed to optimize visual performance by stabilizing the resistor ladders used for gamma correction in display drivers.

Replacement Considerations

The ADD8504WRUZ and ADD8505WRUZ are compatible members of the same series but offer fewer channels. Designers must verify pinout compatibility and channel count requirements when substituting these parts. No other direct substitutes are documented in the provided datasheet.
