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.
