ADD8707WCPZ-REEL7

Overview

The ADD8707WCPZ-REEL7 is a 12-channel gamma buffer with VCOM and regulator, designed for LCD TV and monitor panels. It operates on a single supply of 7.5 V to 16 V. The device features mask-programmable gamma resistors with 0.2% resolution and 0.1% accuracy, alongside a mask-programmable voltage regulator with 0.4% accuracy. Upper six buffers swing to VDD, while lower six swing to GND. Gamma current drive is 15 mA per channel, and VCOM peak output current is 250 mA. It is housed in a 48-lead Pb-free LFCSP package.

Feature Summary

Integrates 12 precision gamma reference outputs with high current drive capabilities.
Features mask-programmable internal resistor strings for accurate gamma curve generation.
Includes an onboard low dropout linear regulator to isolate the gamma curve from supply ripple.
Provides dedicated VCOM amplifier output with high peak current sourcing and sinking.

Applications

LCD TV panel source drivers
LCD monitor panel source drivers

Procurement Notes

Verify the specific ordering suffix 'REEL7' confirms the reel packaging format. Confirm the 'W' indicates wide temperature range operation and 'CPZ' denotes the lead-free LFCSP package. Ensure the development version requirements are met if external tap point programming is needed. Check datasheet for thermal pad soldering requirements to ensure proper heat dissipation during operation.

Selection Notes

Select this component when designing LCD driver circuits requiring integrated gamma correction and VCOM generation. The mask-programmable nature requires submitting a request form for custom tap points and regulator voltages prior to manufacturing. Consider the 48-lead LFCSP package size and thermal resistance characteristics for PCB layout planning.

Part Context

This part belongs to Analog Devices' family of LCD gamma buffer solutions. It integrates functions typically handled by multiple discrete components, reducing board space and improving accuracy. The development version allows for external resistor programming before final mask customization.
