Overview
The LM1207AN is a National Semiconductor video amplifier integrated circuit designed for high-resolution RGB monitor applications. It integrates three matched video amplifiers within a single package, ensuring consistent performance across channels. The device operates on a single or dual supply voltage ranging from 10.8V to 13.2V and draws a supply current of 90 mA. Packaged in a 28-pin DIP with a 0.600-inch width, it is intended for through-hole PCB mounting.
Feature Summary
- Integrates three matched video amplifiers for consistent channel performance
- Designed specifically for high-frequency video signal processing
- Suitable for high-resolution RGB monitor applications
Applications
- High-resolution RGB monitor systems
- Video signal distribution circuits
- Professional video equipment
Procurement Notes
Verify the manufacturer origin carefully, as National Semiconductor assets were acquired by Texas Instruments. Confirm the specific suffix 'AN' corresponds to the 28-DIP package and through-hole mounting requirements. Ensure compatibility with the specified 10.8V to 13.2V supply range before integration into existing designs.
Selection Notes
Select this component when a multi-channel video amplifier with matched characteristics is required for analog video signals. It is appropriate for designs needing three synchronized video paths without external matching components. Consider the 28-DIP package size and through-hole mounting constraints during PCB layout planning.
Part Context
This part belongs to the LM1205/LM1207 family of very high-frequency video amplifier systems. These devices are engineered to provide precise gain and bandwidth for professional video applications. The LM1207AN specifically offers three amplifier channels, distinguishing it from single-channel alternatives in the same series.
Replacement Considerations
Check for direct pin-compatible substitutes from Texas Instruments if National Semiconductor stock is unavailable. Verify that any replacement maintains the 28-DIP package and matches the electrical specifications for video frequency response.
