The HI2315 is a 10-bit, 80MHz, high speed, low power CMOS
D/A converter. The converter incorporates a 10-bit input data
register with current outputs. The HI2315 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.
