Check for Samples: BUF18830

FEATURES

DESCRIPTION

The BUF18830 offers 18 programmable gamma

channels and two programmable V_COMchannels.

•

10-BIT RESOLUTION

18-CHANNEL P-GAMMA:

•

All gamma and V_COMchannels 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.

300-mV Min Swing-to-Rail (10 mA)

TWO-CHANNEL P-V_COM

400-mA Typical I_OUT

•

–

•

HIGH SLEW RATE V_COM: 45 V/μs

RAIL-TO-RAIL OUTPUT

LOW SUPPLY CURRENT

SUPPLY VOLTAGE: 6.5 V to 20 V

DIGITAL SUPPLY: 2.0 V to 5.5 V

TWO-WIRE INTERFACE: Supports 400 kHz and

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.
