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.

... T The units are ppm per degree C. Detailed Description The HI5628 is a dual, 8-bit, current out, CMOS, digital to analog converter. Its maximum update rate is 125MSPS and can be powered by either single or dual power supplies in the recommended range of +3V to +5V. It consumes less than 330mW of power when using a +5V supply with the data switching at 100MSPS ...

... Digital Inputs and Termination The HI5628 digital inputs are guaranteed to CMOS levels. However, TTL compatibility can be achieved by lowering the supply voltage to 3V due to the digital threshold of the input buffer being approximately half of the supply voltage. The internal register is updated on the rising edge of the clock. To minimize reflections, proper termination should be implemented ...
