ADD8709ASTZ-REEL

Overview

The ADD8709ASTZ-REEL is an 18-channel integrated gamma reference generator designed for LCD TV and monitor panels. It features high current drive and low offset voltage to provide accurate and stable gamma curves. The device includes a mask-programmable voltage regulator with 0.4% accuracy, isolating the gamma curve from supply ripple. It operates on a single supply of 7.5 V to 16.5 V, providing 15 mA per channel with a peak output current of 150 mA. The upper nine buffers swing to VDD, while the lower nine swing to GND.

Feature Summary

Integrates 18 precision gamma reference outputs with high current drive capability
Includes an onboard voltage regulator to isolate the gamma curve from supply ripple
Features split buffer architecture where upper channels swing to VDD and lower channels swing to GND

Applications

LCD TV panels
LCD monitor panels

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required temperature range and packaging format. Ensure compliance with RoHS standards and check for any design-in warnings regarding new versus existing designs.

Selection Notes

Select this component when designing source drivers for large LCD panels requiring optimized gamma curves. Consider the thermal resistance and power dissipation limits during layout. Verify that the external resistor values align with the desired gamma voltage points and that the operating temperature range meets system requirements.

Part Context

This part belongs to the ADD8709 family of gamma buffer ICs manufactured by Analog Devices Inc. It is specifically engineered for display applications, offering a complete solution for generating precise gamma voltages. The device simplifies panel design by integrating both the buffer amplifiers and the necessary voltage regulation in a single package.
