The HI5728 is a 10-bit, dual 125MSPS D/A converter which
is implemented in an advanced CMOS process. It 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
• CMOS Compatible Inputs
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 DAC is a member of the
CommLink™ family of communication devices.
