RGB Video Amplifier for Monitors

Monolithic IC MM1375

Outline

This IC is a wideband RGB video amplifier with DC control, developed for use in monitors. It has a differential
input comparator for brightness adjustment, and three matched DC control attenuators for contrast
adjustment. All DC control input is high impedance, and the operating range is set for easy interface with
serial bus control systems, at 0~4V. Also, the building-in blanking circuit clamps video output to less than

0.2V during blanking, enabling blanking on the CRT cathode.

Features

1. Low power consumption (VCC=8V, ICC=68mA)

2. Smaller capacity for clamping capacitor (0.1µF)

3. High band video amp 100MHZ @

4. Matched (±0.1dB) contrast adjustment attenuators built in

5. Built-in cutoff and brightness adjustment input comparators using external gate control

6. Built-in high input impedance DC contrast control, 0~4V

7. Output blanking function

8. Output can drive hybrid or discrete CRT driver directly
