The HI5780 is a 10-bit, 80 MSPS, high speed, low power
CMOS D/A converter. The converter incorporates a 10-bit input
data register with current outputs. The HI5780 includes a power
down feature that reduces power consumption and a blanking
control. The on-chip bandgap reference can be used to set the
output current range of the D/A.
