ADD8506WRUZ-REEL7

Overview

The ADD8506WRUZ-REEL7 is a six-channel LCD gamma reference buffer manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 3.3 V to 6.5 V and features rail-to-rail input and output capabilities. The device provides a high output current of 380 mA and maintains a low supply current of 3.9 mA. It is designed to be stable with loads up to 1 nF and functions within a temperature range of −40°C to +105°C. Packaged in a 24-lead Pb-free TSSOP, this specific variant is supplied in a 7-inch tape and reel format.

Feature Summary

• Six independent channels with A/B muxed inputs for selecting between two external gamma voltage curves
• High slew rate and drive capability to ensure stability of the reference ladder network
• Rail-to-rail input and output architecture supporting wide dynamic signal ranges
• Low power consumption with minimal supply current draw during operation

Applications

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

Procurement Notes

Verify that the component matches the commercial grade specification rather than the automotive version (ADD8506WWARUZR7), as specifications may differ. Confirm the package option corresponds to the 24-lead Thin Shrink Small Outline Package. Ensure the ordering suffix indicates the 7-inch tape and reel configuration for automated assembly processes.

Selection Notes

Select this component when driving column driver gamma inputs for line inversion displays requiring six buffered channels. The rail-to-rail performance and high output current are suitable for stabilizing resistor ladders to optimize gray scale and visual performance. Consider the operating temperature range and single-supply requirements against system constraints.

Part Context

This part 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 packaging options, differing primarily in channel count and pin configurations.
