Overview
The ADD8710ARUZ-REEL is a 10-channel gamma buffer with an integrated VCOM driver designed for high-resolution TFT LCD panels. It operates from a single supply voltage ranging from 4.5 V to 18 V and is housed in a compact 28-lead TSSOP package. The device features a maximum offset voltage of 12 mV and a slew rate of 8 V/μs. Gamma buffers provide continuous output currents exceeding 10 mA, while the VCOM driver delivers up to 250 mA peak current. Total supply current is approximately 10 mA at no load.
Feature Summary
- Integrates ten independent gamma buffers alongside a dedicated VCOM driver within a single component.
- Capable of driving large capacitive loads typical of TFT LCD panel architectures.
- Supports wide single-supply operation suitable for various display power requirements.
- Designed as a drop-in replacement for legacy buffer solutions.
Applications
- TFT LCD monitor panels
- TFT LCD notebook panels
Procurement Notes
Verify that the specific part number matches the required reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor channels. Ensure the ordering suffix aligns with the desired tape and reel specifications before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring multiple buffered outputs for gamma correction and common mode voltage generation. Evaluate thermal resistance characteristics relative to the PCB layout constraints. Consider the operating temperature range and supply voltage limits to ensure compatibility with the target display system architecture.
Part Context
This component belongs to the Analog Devices family of precision amplifiers and buffer drivers specialized for display applications. It utilizes an advanced high-voltage CBCMOS process to achieve performance metrics suitable for demanding visual interface environments.
Replacement Considerations
The datasheet identifies the BUF11702 as a compatible drop-in replacement candidate. Verify pinout compatibility and electrical parameter alignment before substituting existing designs.
