LM1237 - 150 MHz I2C Compatible RGB Preamplifier

Download the LM1237 datasheet PDF. This datasheet also covers the LM1 variant, as both devices belong to the same 150 mhz i2c compatible rgb preamplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM1237 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.

LM1237 150 MHz I2C Compatible RGB Preamplifier with Internal 254 Character OSD and 4 DACs September 2002 LM1237 150 MHz I2C Compatible RGB Preamplifier with Internal 254 Character OSD and 4 DACs General Description The LM1237 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 LM1237 preamp is also designed to be compatible with the LM246x high gain driver family.
