Overview

LM1247 150 MHz I2C Compatible RGB Preamplifier with Internal 512 Character OSD ROM, 512 Character RAM and 4 DACs December 2002 LM1247 150 MHz I2C Compatible RGB Preamplifier with Internal 512 Character OSD ROM, 512 Character RAM and 4 DACs General Description The LM1247 pre-amp is an integrated CMOS CRT preamp.
It has an I2C compatible interface which allows control of all the parameters necessary to directly setup and adjust the gain and contrast in the CRT display.
Brightness and bias can be controlled through the DAC outputs which are well matched to the LM2479 and LM2480 integrated bias clamp ICs.
The LM1247 preamp is also designed to be compatible with the LM246x high gain driver fami...
