MAX9669ETI/V+

Video Processing Overview

The MAX9669ETI/V+ 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 dedicated DACs. 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

• Integrated multiple-time programmable (MTP) memory eliminates external EEPROM requirements
• Programmable VCOM limits allow defined low and high range constraints
• High-speed settling reduces recovery time during critical display patterns
• On-chip lowpass filter significantly reduces horizontal line frequency noise

Video Processing Applications

• TFT LCD panels
• Automotive displays

Video Processing Procurement Notes

Verify the automotive qualification suffix '/V' against specific project requirements. Confirm that the 28-pin TQFN-EP package footprint matches the design layout. Ensure the operating temperature range of -40°C to +85°C aligns with environmental specifications.

Video Processing Selection Notes

Select this component when a single-chip solution is required to replace discrete gamma buffers, VCOM amplifiers, and linear regulators. The integrated MTP memory simplifies production calibration by storing values directly on the chip. Verify power supply compatibility with the specified 9V to 20V analog range.

Video Processing Part Context

This device belongs to the MAX9669 series of video gamma reference systems. The '/V' suffix indicates automotive qualification. The standard 'MAX9669ETI+' variant shares identical electrical characteristics but lacks the specific automotive certification associated with the '/V' designation.

Video Processing Replacement Considerations

Public confirmed substitute part numbers: None.
