Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX9669ETI outputs 16 reference voltages for gamma correction of TFT LCD displays and one voltage reference for VCOM. each gamma reference has a 10-bit digital/analog converter (DAC) and corresponding buffer to ensure stable system operation. the VCOM reference voltage has its own 10-bit DAC and amplifier to ensure stable voltages are maintained during critical levels and stencil display. The MAX9669ETI features integrated multiple-times-programmable (MTP) memory for on-chip storage of gamma and VCOM values, eliminating the need for an external EEPROM.The MAX9669ETI's on-chip non-volatile memory supports up to 100 write operations.

The gamma output provides a peak transient current drive of 200mA, stabilising within 1µs, and the VCOM output provides a peak transient current drive of 600mA, also stabilising within 1µs. The analogue supply voltage range is between 9V and 20V and the digital supply voltage range is between 2.7V and 3.6V.

Gamma and VCOM values are programmed into registers via the I²C interface.

MAX9669ETI Applications

TFT-LCD

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
