The BUF20800-Q1 is a programmable voltage reference generator designed for gamma correction in TFT-LCD panels. It provides 18 programmable outputs for gamma correction and two channels for VCOM adjustment, each with 10-bit resolution.
All channels are programmable using an I2C interface that
supports high-speed data transfers up to 3.4 MHz.
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 changes are easily implemented without hardware
changes.
The BUF20800-Q1 uses TI’s latest, small-geometry analog CMOS process, which makes it a very competitive choice for full production, not just evaluation.
For lower channel count, please contact your local sales or marketing representative.
The BUF20800-Q1 is available in an HTSSOP-38 package withPowerPAD™. It is specified from −40°C to +105°C.
