The LM1875 is a monolithic power amplifier offering very low distortion and high quality performance for consumer audio applications. The LM1875 delivers 20 watts into a 4Ω or 8Ω load on ±25V supplies. Using an 8Ω load and ±30V supplies, over 30 watts of power may be delivered. The amplifier is designed to operate with a minimum of external components. Device overload protection consists of both internal current limit and thermal shutdown. The LM1875 design takes advantage of advanced circuit techniques and processing to achieve extremely low distortion levels even at high output power levels. Other outstanding features include high gain, fast slew rate and a wide power bandwidth, large output voltage swing, high current capability, and a very wide supply range.

The LM1253A pre-amp is an integrated high voltage triple CRT pre-amp and Analog On Screen Display (OSD) generator. The IC is I2C controlled, and allows control of all the parameters necessary to setup and adjust the brightness and contrast in the CRT display. In addition, it provides a programmable period vertical blanking pulse which is used to blank the G1. The LM1253A pre-amp is designed to work in cooperation with the LM2453 driver, and provides a multiplexed video signal (VideoPlex) interface to enable the DC clamp levels at the cathode to be varied in order to set up the CRT bias and to allow individual adjustment for brightness. The Analog OSD has a selectable palette allowing a wide selection of colors. The preset level of the OSD can be controlled by I2C to suit different CRT displays. The OSD signal is internally mixed with the video signal, before the gain section, and thus gives excellent white tracking of the OSD with the white color point setting of the video. The Brightness settings are also mixed into the video signal before the gain matching controls and consequently give excellent white color point tracking with variations in the Brightness control. An active horizontal blanking signal is added to the video at the output, giving excellent smear performance, and preventing video content dependency

The LM1262 is an integrated CMOS CRT pre-amp that supports the I2C interface and allows direct control of all the parameters necessary to set up 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 LM1262 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 pream- plifier 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.
