LM1267
150 MHz I
2C Compatible RGB Video Amplifier System
with OSD and DACs
General Description
The LM1267 pre-amp is an integrated CMOS CRT pre-amp.
The IC is I
2C compatible, and allows control of all the pa-
rameters necessary to directly setup and adjust the gain and
contrast in the CRT display. Brightness and bias can be
controlled through the DAC outputs, and is well matched to
the LM2479 and LM2480 integrated bias clamp IC.
The LM1267 pre-amp is designed to work in cooperation
with the LM246X high gain driver family.
Black level clamping of the signal is carried out directly on
the AC coupled input signal into the high impedance pream-
plifier input, thus eliminating the need for additional black
level clamp capacitors.
The IC is packaged in an industry standard 24-lead DIP
molded plastic package.
