DESCRIPTION

LOW SUPPLY CURRENT: 900µA/ch

SUPPLY VOLTAGE: 7V to 18V

DIGITAL SUPPLY: 2.3V to 5.5V

The BUF12800 is a programmable voltage reference

generator designed for dynamic gamma correction in

TFT-LCD panels. It provides 12 programmable outputs,

each with 10-bit resolution.

INDUSTRY-STANDARD TWO-WIRE INTERFACE

− High-Speed Mode: 3.4MHz

TI’s new, small geometry, state-of-the-art, analog CMOS

process allows the use of one digital-to-analog converter

(DAC) per channel while still maintaining a very small chip

size. This topology has the advantage of significantly

increased programming speed over existing program-

mable buffers.

HIGH ESD RATING:

− 4kV HBM, 1kV CDM, 200V MM

DEMO BOARD AND SOFTWARE AVAILABLE

Programming of each output occurs through an industry-

standard, two-wire serial interface. Unlike existing

programmable buffers, the BUF12800 offers a high-

speed, two-wire interface mode that allows clock speeds

up to 3.4MHz. The BUF12800 features a double-buffered

DAC register structure that significantly simplifies imple-

mentation of dynamic gamma control. This further reduces

programming time, especially when many channels have

to be updated simultaneously.

Reference pins set the high and low voltages of the output

range. They are internally buffered, which simplifies

design. They may be connected to external resistors to

divide the output range for finer resolution of outputs.

The BUF12800 is available in a TSSOP-24 PowerPAD

package. It is specified from −40°C to +85°C.
