HI5628
8-Bit, 125/60MSPS, Dual High Speed
CMOS D/A Converter
The HI5628 is an 8-bit, dual 125MSPS D/A converter which
is implemented in an advanced CMOS process. Operating
from a single +5V to +3V supply, the converter provides
20.48mA of full scale output current and includes an input
data register. Low glitch energy and excellent frequency
domain performance are achieved using a segmented
architecture. The single DAC version is the HI5660 while
10-bit versions exist in the HI5760 and HI5728.
