BUF16821AIPWPRQ1 Product Details

TFT-LCD Reference Drivers

PowerPAD is a trademark of Texas Instruments. I2C is a trademark of NXP Semiconductors. All other trademarks are the property of their respective owners.

Description

The BUF16821AIPWPRQ1 offers 16 programmable gamma channels and two programmable VCOM channels. The final gamma and VCOM values can be stored in the on-chip, nonvolatile memory. To allow for programming errors or liquid crystal display (LCD) panel rework, the device supports up to 16 write operations to the on-chip memory.

The device has two separate memory banks, allowing simultaneous storage of two different gamma curves to facilitate switching between gamma curves. All gamma and VCOM channels offer a rail-to-rail output that typically swings to within 150 mV of either supply rail with a 10-mA load. All channels are programmed using an I2C interface that supports standard operations up to 400 kHz and high-speed data transfers up to 2.7 MHz.

The device is manufactured using Texas Instruments’ proprietary, state-of-the-art, high-voltage CMOS process. This process offers very dense logic and high supply voltage operation of up to 20 V. The device is offered in an HTSSOP-28 PowerPAD package, and is specified from –40°C to +85°C.
