The HI1171 is an 8-bit, 40MHz, high speed D/A converter.
The converter incorporates an 8-bit input data register with
blanking capability, and current outputs. The HI1171 fea-
tures low glitch outputs. The architecture is a current cell
arrangement to provide low linearity errors.
The HI1171 is available in an Industrial temperature range
and is offered in a 24 lead (200 mil) SOIC plastic package.
For dual version, please refer to the HI1177 Data Sheet.
For triple version, please refer to the HI1178 Data Sheet.
