LM1269

110 MHz I²C Compatible RGB Video Amplifier System

with OSD & DACs

n 110 MHz bandwidth preamplifier with full video signal

parametric control

General Description

The LM1269 pre-amp is an integrated CMOS CRT pre-amp.

n 4 external 8-bit DACs for bus controlled Bias and

The IC is I²C compatible, and allows control of all the pa-

Brightness

rameters necessary to directly setup and adjust the gain and

n Suitable for use with discrete or integrated clamp, with

contrast in the CRT display. Brightness and bias can be

software configurable Brightness mixer

controlled through the DAC outputs, and is well matched to

the LM2479 and LM2480 integrated bias clamp IC.

n Power Save (Green) Mode, 80% power reduction

n Matched to LM246X driver

The LM1269 pre-amp is designed to work in cooperation

with the LM246X high gain driver family.

Applications

Black level clamping of the signal is carried out directly on

n Low end 14’, 15’, and 17’ bus controlled monitors with

the AC coupled input signal into the high impedance pream-

plifier input, thus eliminating the need for additional black

level clamp capacitors.

OSD

n 1024 X 768 displays up to 70 Hz requiring OSD

capability

n Very low cost system with LM246X driver

The IC is packaged in an industry standard 24-lead DIP

molded plastic package.

Features

n I²C compatible interface
