APPLICATION INFORMATION
At power-on, the BUF08821 first updates all channels
to midscale (code 1000000000) and then reads the

approximately 560
μs. After this read is complete, the
programmable gamma reference outputs and one
BUF08821 updates the DACs simultaneously with
VCOM output, each with 10-bit resolution. The
data for the bank selected by the BKSEL pin.
BUF08821 is programmed through a high-speed, I2C
The BUF08821 can be powered using an analog
interface. The final gamma and VCOM values can be
supply voltage from 9V to 20V, and a digital supply
stored in the on-chip, nonvolatile memory. To allow
from 2V to 5.5V. The digital supply must be applied
for programming errors or liquid crystal display (LCD)
before the analog supply to avoid excessive current
panel rework, the BUF08821 supports up to 16 write
and power consumption, or possibly even damage to
operations to each word in the on-chip memory. The
the device if left connected only to the analog supply
BUF08821 has two separate memory banks, allowing
for extended periods of time. Figure 10 shows a
simultaneous storage of two different gamma curves
typical configuration of the BUF08821.
to facilitate dynamic switching between gamma
curves. The BUF08821 also has two storage registers
for each digital-to-analog converter (DAC) channel to
allow fast switching (less than 10
μs) between gamma
curves.
(1) RC combination optional; see the Output Pins ESD Protection Current-Steering Diodes section.
(2) GNDA and GNDD must be connected together.
(3) Pins 6 and 15 are VS. The one set of capacitors shown on pin 15 are common to both pins.
