DESCRIPTION

The BUF18830 offers 18 programmable gamma

channels and two programmable VCOM channels.

All gamma and VCOM channels offer a rail-to-rail

output that typically swings to within 300 mV of either

supply rail with a 10-mA load. All channels are

programmed using a two-wire interface that supports

standard operations up to 400 kHz and high-speed

data transfers up to 3.4 MHz.

The BUF18830 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 20 V. The

BUF18830 is offered in a QFN-38 package and is

specified from –40°C to +85°C.
