Video Processing datasheet and documents for MAX1512ETA+T
Video Processing Overview
The MAX1512ETA+T is an EEPROM-programmable TFT VCOM calibrator designed for thin-film transistor liquid-crystal displays. It replaces mechanical potentiometers by sinking a programmable current to set the VCOM voltage level. The device features a single-wire interface for adjustment and programming, utilizing an internal 7-bit DAC that is ratiometric relative to AVDD. It operates with a logic supply range of 2.6V to 3.6V and an analog supply range of 4.5V to 20V. The component is housed in an 8-pin 3mm x 3mm TDFN package.
Video Processing Feature Summary
- EEPROM storage retains VCOM settings across power cycles
- Single-wire interface delivers power and commands
- Guaranteed monotonic output over operating range
Video Processing Applications
- LCD Panels
- Notebook Computers
- Monitors

Video Processing Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm lead-free status associated with the '+' designation. Ensure the temperature grade matches the -40°C to +85°C specification. Validate the manufacturer origin as Analog Devices Inc./Maxim Integrated.
Video Processing Selection Notes
Select this component when replacing mechanical potentiometers in TFT LCD backplanes. It is suitable for applications requiring automated VCOM calibration. Consider the 7-bit resolution and external resistor requirements for setting the full-scale sink current range.
Video Processing Part Context
This part belongs to the MAX1512 family of solid-state VCOM adjusters. It serves as a direct replacement for manual tuning components in display manufacturing. The design simplifies production by enabling digital control of the display backplane voltage through a microcontroller or dedicated programmer.
Video Processing Replacement Considerations
Direct substitutes include other Maxim Integrated TFT VCOM calibrators. Verify pin compatibility and electrical specifications before swapping. Check for updated revisions or alternative packages if the TDFN form factor is unavailable.
Video Processing FAQ
How is the VCOM level adjusted?
The VCOM level is adjusted by pulsing the CTL pin low or high for more than 200µs to increment or decrement the internal DAC setting.
What is the function of the SET pin?
The SET pin connects to an external resistor (RSET) that sets the full-scale adjustable sink current, determining the minimum VCOM value.
