DESCRIPTION

LOW SUPPLY CURRENT: 1mA/ch

SUPPLY VOLTAGE: 8.5V to 18V

DIGITAL SUPPLY: 2.0V to 5.5V

INDUSTRY-STANDARD, TWO-WIRE

The BUF16820 is a programmable voltage reference

generator designed for gamma correction in TFT-LCD

panels. It provides 14 programmable outputs and two

V_COMchannels, each with 10-bit resolution. It offers

on-chip, one-time programmable (OTP) memory that

allows the user to store the gamma voltages on-chip. This

eliminates the need for an external EEPROM.

INTERFACE: 3.4MHz HIGH-SPEED MODE

HIGH ESD RATING:

4kV HBM, 1kV CDM, 200V MM

DEMO BOARD AND SOFTWARE AVAILABLE

This programmability replaces the traditional, time-

consuming process of changing resistor values to optimize

the various gamma voltages, and allows designers to

determine the correct gamma voltages for a panel very

quickly. Required voltage changes can also be easily

implemented without changing the hardware.

BUF16820

The BUF16820 uses TI’s latest, small-geometry analog

CMOS process, which makes it a very competitive choice

for full production, not just evaluation.

REFH OUT

OUT1

Programming of each output occurs through an industry-

standard, two-wire serial interface. Unlike existing

programmable buffers, the BUF16820 offers a high-speed

mode that allows clock speeds up to 3.4MHz.
