Video Processing datasheet and documents for MAX9665ETP+
Video Processing Overview
The MAX9665ETP+ is a 20-pin TQFN-EP integrated circuit providing six programmable gamma correction channels and one VCOM driver. It features 10-bit DACs with high peak transient current capabilities to reduce output voltage recovery time during critical display patterns. The device operates within an analog supply range of 9V to 22V and a digital supply of 2.7V to 3.6V, supporting temperatures from -40°C to +85°C.
Video Processing Feature Summary
- Integrates multiple-time programmable (MTP) memory for nonvolatile storage of gamma and VCOM codes, eliminating external EEPROM requirements.
- Provides high peak transient current on the VCOM channel to stabilize voltage levels during rapid display pattern changes.
- Supports I2C programming for full register control and single-wire interface for legacy flicker adjustment compatibility.
Video Processing Applications
- TFT LCD panel driving
- Gamma correction circuits
- VCOM reference generation
Video Processing Procurement Notes
Verify the specific package marking and date code against the manufacturer's latest documentation to ensure authenticity. Confirm that the exposed pad connection meets thermal management requirements for the target application environment.
Video Processing Selection Notes
Select this component when a single-chip solution is required to replace discrete variable resistors, linear regulators, and buffers in TFT-LCD designs. Ensure the design accommodates the high-voltage analog supply requirements and utilizes the MTP memory for production calibration.
Video Processing Part Context
Part of the MAX9665/MAX9666/MAX9667 family offering 6, 8, and 10 gamma channels respectively. All variants share the same 20-TQFN-EP package and core functionality, differing primarily in the number of available gamma output pins.
