DESCRIPTION

The BUF16821 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 BUF16821 supports up to 16 write operations to the on-chip memory.

The BUF16821 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 150mV of either

supply rail with a 10mA load. All channels are

programmed using an I2C interface that supports

standard operations up to 400kHz and high-speed

data transfers up to 3.4MHz.

The BUF16821 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 20V. The

BUF16821 is offered in a HTSSOP-28 PowerPAD™

package, and is specified from –40°C to +85°C.
