FEATURES  
DESCRIPTION  
2
10-BIT RESOLUTION  
The BUF12840 offers 12 programmable gamma  
channels with external electrically erasable  
programmable read-only memory (EEPROM) read  
capabilities.  
12-CHANNEL P-GAMMA  
READS FROM EXTERNAL EEPROM  
TWO INDEPENDENT PIN-SELECTABLE  
MEMORY BANKS  
The BUF12840 has two separate memory banks that  
allow simultaneous storage of two different gamma  
curves to facilitate switching between gamma curves.  
RAIL-TO-RAIL OUTPUT:  
300mV Min Swing-to-Rail (10mA)  
200mV Min Swing-to-Rail (5mA)  
All gamma channels offer a rail-to-rail output that  
typically swings to within 200mV of either supply rail  
with a 5mA load. All channels are programmed using  
a two-wire interface that supports standard operations  
up to 400kHz and high-speed data transfers up to  
3.4MHz.  
LOW SUPPLY CURRENT  
SUPPLY VOLTAGE: 9V to 20V  
DIGITAL SUPPLY: 2V to 5.5V  
TWO-WIRE INTERFACE: Supports 400kHz and  
3.4MHz Operation  
The BUF12840 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  
BUF12840 is offered in a QFN-24 package, and is  
specified from –40°C to +95°C.
