HI1178 Datasheet – 3-Channel D/A Converter
Triple 8-Bit, 40MSPS, RGB, 3-Channel D/A Converter
HI1178 overview
The HI1178 is a Triple 8-Bit, 40MSPS, RGB, 3-Channel D/A Converter made by Intersil Corporation, supplied in a 48 Ld MQFP package. Main ratings: Resolution Triple 8-Bit; Maximum Conversion Speed 40MHz; Differential Linearity Error +0.3 LSB; Low Power Consumption 240mW. This page brings together the HI1178 pinout and key specifications, with the full datasheet PDF to preview below or download.
The HI1178 is a triple 8-bit, high-speed, CMOS 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 device operational. A bias voltage generator is internal. Each channel clock input can be controlled individually, or connected together as one. The HI1178 also has BLANK video control signal.
