General Description

The LM1229 pre-amp is an integrated CMOS CRT RGB preamp plus horizontal and vertical deflection processing with an I2C compatible interface for controlling all the parameters necessary to directly adjust the gain, contrast and brightness and geometry of the CRT display.

In the RGB section, the CRT bias is controlled by the three DAC outputs which are matched to the LM248x integrated bias clamp ICs.

The brightness control operates on the video channels rather than the bias channels and is designed to maintain the CRT color temperature through the full range of adjustment.
