General Description
The LM1269 pre-amp is an integrated CMOS CRT pre-amp. The IC is I2C compatible, and 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, and is well matched to the LM2479 and LM2480 integrated bias clamp IC.
The LM1269 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 preamplifier 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.
