MAX9669ETI+

Video Processing Overview

The MAX9669ETI+ is a 10-bit programmable gamma reference system with integrated MTP memory for TFT LCDs. It provides 16 gamma correction channels and one VCOM driver, each with a dedicated 10-bit DAC. The analog supply voltage ranges from 9V to 20V, while the digital supply operates between 2.7V and 3.6V. Gamma outputs settle within 1µs and support 200mA peak transient current. The VCOM output settles within 1µs and supports 600mA peak transient current. Configuration is managed via an I²C interface.

Video Processing Feature Summary

• Integrates 16-channel gamma correction and VCOM driver with individual 10-bit DACs
• Includes on-chip multiple-time programmable (MTP) memory to eliminate external EEPROM
• Supports high-speed settling and peak current delivery for critical display patterns
• Features programmable VCOM limits and thermal shutdown protection

Video Processing Applications

• TFT LCD panels requiring precise gamma correction
• Display systems needing integrated VCOM generation
• Production lines utilizing automatic panel-by-panel calibration

Video Processing Procurement Notes

Verify the specific suffix ETI+ indicates a lead-free/RoHS-compliant package in the 28-pin TQFN-EP form factor. Confirm the operating temperature range of -40°C to +85°C matches the application requirements. Ensure the device version aligns with the intended manufacturing standards and regional compliance regulations.

Video Processing Selection Notes

Select this component when a single IC solution is required to replace discrete gamma buffers, VCOM amplifiers, and resistor strings. It is suitable for designs demanding low horizontal line frequency noise due to internal DAC filtering. Consider the exposed pad requirement for proper thermal management and ground connection during PCB layout.

Video Processing Part Context

This device belongs to Maxim Integrated's portfolio of display driver solutions designed for thin-film transistor liquid crystal displays. It consolidates multiple analog functions into a compact package, reducing bill-of-materials complexity. The integration of nonvolatile memory allows for factory programming of display-specific parameters without external storage components.
