National Semiconductor LM1267 150 MHz I2C Compatible RGB Video Amplifier System with OSD DACs Datasheet
The LM1267 is an integrated CMOS pre‑amplifier designed for CRT displays. It provides I²C‑compatible control of gain, contrast, brightness and black‑level, and works with the LM246X driver family. The device is packaged in a 24‑lead DIP.
Key features include a programmable bandwidth of 110 MHz to 150 MHz, four external 8‑bit DACs for bias and brightness control, a power‑save mode that reduces consumption by 80 %, and extensive OSD functionality with selectable video or OSD inputs.
