LM1246 General Description

The LM1246 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.
