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.
