Description

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.
