MAX9674ETI+T

Video Processing Overview

The MAX9674ETI+T is a 10-bit programmable gamma reference system designed for TFT LCDs. It provides 16 gamma correction channels and one VCOM driver, each with dedicated DACs. The device features integrated multiple-time programmable (MTP) memory to store calibration values, eliminating external EEPROM requirements. It operates with an analog supply range of 9V to 20V and a digital supply of 2.7V to 3.6V. Gamma outputs settle within 1µs with 200mA peak current capability, while the VCOM output supports 600mA peak transient current. Configuration is managed via an I²C interface.

Video Processing Feature Summary

• Integrated MTP memory stores gamma and VCOM calibration data on-chip, removing the need for external nonvolatile storage.
• Dedicated 10-bit DACs drive gamma buffers and a VCOM amplifier to ensure stable voltage references during critical display patterns.
• I²C serial interface allows programming of registers and MTP memory for automatic panel-by-panel calibration.

Video Processing Applications

• TFT LCD panels requiring precise gamma correction
• Display systems needing integrated VCOM generation
• Production lines utilizing automatic gamma and flicker calibration

Video Processing Procurement Notes

Verify the component designation matches the specific pin count and package type required for your design. Confirm that the operating temperature range meets your environmental specifications. Ensure power supply decoupling capacitors are placed close to the AVDD and DVDD pins as recommended in the datasheet. Check for any lead-free or RoHS compliance markings if required by your manufacturing standards.

Video Processing Selection Notes

Select this component when a single chip solution is needed to replace discrete DVRs, VCOM amplifiers, and linear regulators. Consider the 16-channel gamma output capacity and high peak current capabilities for driving large or high-resolution displays. Evaluate the thermal performance under maximum load conditions to ensure operation within the specified junction temperature limits.

Video Processing Part Context

This device belongs to the MAX9672/MAX9673/MAX9674 family of 10-bit programmable gamma reference systems. The MAX9674 variant specifically offers 16 gamma channels plus a VCOM driver, distinguishing it from the 12-channel MAX9672 and 14-channel MAX9673. All variants share the same 28-pin TQFN-EP package and core functionality.
