Description
General part information
BUF16821-Q1 Series
The BUF16821-Q1 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.
