Description

The HI5728 is a 10-bit, dual 125MSPS D/A converter which is implemented in an advanced CMOS process. HI5728 is designed for high speed applications where integration, bandwidth and accuracy are essential. Operating from a single +5V or +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. A 60MSPS version and an 8-bit (HI5628) version are also available. Comparable single DAC solutions are the HI5760 (10-bit) and the HI5660 (8-bit). This HI5728 DAC is a member of the CommLink™ family of communication devices.
