Description

The HI1260 is a triple 8-bit, high-speed, bipolar D/A converter designed for video band use. It has three separate, 8-bit pixel inputs, one each for red, green, and blue video data. A single 5.0V power supply and pixel clock input is all that is required to make the HI1260 operational. A bias voltage generator is internal. For lower CMOS power consumption, refer to the HI1178.
