ADD8709WSTZ-REEL7

Overview

The ADD8709WSTZ-REEL7 is an 18-channel integrated gamma reference generator designed for LCD TV and monitor panels. It operates on a single supply voltage ranging from 7.5 V to 16.5 V with a typical supply current of 17 mA. The device features 18 precision buffer outputs, where the upper nine channels swing to VDD and the lower nine swing to GND. Each channel provides a gamma current drive of 15 mA with a peak output current capability of 150 mA. The unit includes a mask-programmable voltage regulator with 0.4% accuracy and operates within a temperature range of –40°C to +105°C.

Feature Summary

Integrates 18 precision gamma reference buffers with high current drive capabilities
Includes an onboard low dropout linear regulator to isolate the gamma curve from supply ripple
Features split buffer architecture allowing upper channels to swing to VDD and lower channels to GND

Applications

LCD TV panels
LCD monitor panels

Procurement Notes

Verify the specific suffix 'W' indicates the extended industrial temperature range of -40°C to +105°C compared to the 'A' variant. Confirm the 'REEL7' designation matches the required tape and reel quantity for your manufacturing line. Ensure the LQFP-48 package dimensions align with your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when designing source drivers for large LCD panels requiring precise gamma correction. The internal regulator simplifies design by providing a stable reference level. Consider the thermal resistance of the LQFP-48 package and calculate power dissipation to ensure junction temperatures remain within safe operating limits under maximum load conditions.

Part Context

This part belongs to the ADD8709 family of 18-channel gamma buffers manufactured by Analog Devices Inc. It is specifically engineered to correct non-ideal gamma curves in source drivers, ensuring consistent panel performance. The device replaces discrete resistor networks and multiple amplifiers, offering a compact solution for display driver ICs.
