Description
The HI20206 is a triple 8-bit, high-speed, bipolar D/A
converter designed for video band use. It has three sepa-
rate, 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 device operational. A bias
voltage generator is internal. For lower CMOS power
consumption, refer to the HI1178.
