The BUF18830 offers 18 programmable gamma channels and two programmable V_COM channels.

All gamma and V_COM 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.
