The LM1279 is a fully featured and cost-effective video amplifier that includes an On-Screen Display (OSD) functionality. It operates at 8V, ensuring low power consumption and enhanced reliability. The device is provided in a 20-pin dual in-line package (DIP), which is suitable for compact video channel designs that require OSD. All video functions are controlled via high impedance DC inputs ranging from 0V to 4V, facilitating easy interfacing with 5V digital-to-analog converters (DACs) utilized in computer-controlled systems and digital alignment applications. The LM1279 features unique OSD switching, eliminating the need for an OSD switching signal. An OSD signal applied to any of the OSD inputs typically activates the OSD mode within 5 nanoseconds. This video amplifier is ideal for low-cost OSD monitors supporting resolutions up to 1280 x 1024. Additionally, the LM1279 offers superior electrostatic discharge (ESD) protection and serves as an excellent alternative to the MC13282 in new design implementations. This component is manufactured by National Semiconductor Corporation.

The LM1279 video amplifier is designed to meet the demands of modern video applications, particularly where OSD functionality is required. The low operating voltage of 8V not only contributes to reduced power consumption but also enhances the reliability of the device in various operating conditions. The compact 20-pin DIP package allows for easy integration into tight spaces, making it suitable for a wide range of applications, including consumer electronics and industrial equipment.

The control mechanism for the video functions is particularly noteworthy, as it utilizes high impedance DC inputs that can easily interface with standard 5V DACs. This feature simplifies the design process for engineers, enabling seamless integration into existing systems without the need for additional components or complex circuitry.

The OSD functionality is a standout feature of the LM1279. The ability to switch to OSD mode within 5 nanoseconds upon receiving an OSD signal allows for rapid display updates, which is crucial in applications that require real-time information display. This makes the LM1279 an ideal choice for monitors that require quick and efficient OSD capabilities.

Furthermore, the LM1279's robust ESD protection ensures that the device can withstand electrostatic discharges, making it more durable and reliable in environments where such conditions could cause damage to sensitive electronic components. This characteristic is particularly important for devices used in public or industrial settings, where exposure to ESD can be more frequent.

In summary, the LM1279 video amplifier is a versatile and reliable solution for applications requiring OSD functionality, offering ease of integration, rapid response times, and enhanced durability against ESD. Its design and specifications make it a preferred choice for engineers looking to implement low-cost, high-performance video amplification solutions.The LM1279 is a full featured and low cost Video Amplifier with OSD (On Screen Display). 8V operation for low power and increased reliability.
