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.
