DESCRIPTION  
234  
•
10-BIT RESOLUTION  
The BUF08821 offers eight programmable gamma  
channels plus one programmable VCOM channel.  
•
•
•
•
8-CHANNEL P-GAMMA  
1-CHANNEL P-VCOM  
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 BUF08821 supports up to 16 write  
operations to the on-chip memory.  
16x REWRITABLE NONVOLATILE MEMORY  
TWO INDEPENDENT PIN-SELECTABLE  
MEMORY BANKS  
•
RAIL-TO-RAIL OUTPUT:  
300mV Minimum Swing-to-Rail (10mA)  
> 300mA Maximum IOUT  
The BUF08821 has two separate memory banks,  
allowing simultaneous storage of two different gamma  
curves to facilitate switching between gamma curves.  
•
•
•
•
LOW SUPPLY CURRENT  
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.  
SUPPLY VOLTAGE: 9V to 20V  
DIGITAL SUPPLY: 2V to 5.5V  
I2C ™ INTERFACE: Supports 400kHz and  
3.4MHz Clock Frequency  
APPLICATIONS  
The BUF08821 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  
BUF08821 is offered in a HTSSOP-20 PowerPAD ™  
package. It is specified from –40°C to +85°C.
