Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The BUF16821AIPWPRQ1 provides 16 programmable gamma channels, and two programmable VCOM channels. The final gamma and VCOM values can be stored in on-chip, non-volatile memory. The device supports up to 16 write operations to on-chip memory in case of programming errors or to restart the liquid crystal display (LCD) panel.

The device has two separate memory banks that enable simultaneous storage of two different gamma profiles, making switching between gamma profiles easier. All gamma and VCOM channels provide a rail-to-rail output that typically swings within 150mV of either supply rail at 10mA load. All channels can be programmed using an I2C interface that supports standard operation up to 400kHz and high speed data transfer up to 2.7MHz.

The device is fabricated using Texas Instruments' (TI) proprietary, state-of-the-art high-voltage CMOS process. This process provides high density logic and high supply voltage operation up to 20V. The device is available in a heatsink thin small form factor (HTSSOP)-28 PowerPAD package and is rated for operation over the -40°C to +85°C temperature range.

Applications

TFT-LCD reference driver

• 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.
