High Speed, 3-Channel D/A Converter
August 1997
Features
Description
The HI3050 is a triple, 10-bit D/A converter, fabricated in a
silicon gate CMOS process, ideally suited for RGB video
applications.

The converter incorporates three 10-bit input data registers
with a common blanking capability, forcing all outputs to 0mA.
The HI3050 features low glitch, high impedance current out-

linearity errors.
• Low Glitch Energy
The HI3050 requires a 2V external reference and a set
resistor to control the output current. The HI3050 also features
a chip enable/disable pin for reducing power consumption
(<5mW) when the part is not in use.
• CMOS Compatible Inputs
• Direct Replacement for Sony CXD2308
Applications
The HI3050 can generate RS-343A and RS-170 compatible
video signals into doubly terminated and singly terminated
75Ω loads.
• NTSC, PAL, SECAM Displays
• High Definition Television (HDTV)
• Presentation and Broadcast Video
