HI1177
8-Bit, 40MSPS, 2-Channel D/A Converter
The HI1177 is a dual 8-bit CMOS digital-to-analog converter.
It has input/output equivalent to 2 channels of Y and C for
video use or I and Q for modulators.
The HI1177 is available in the industrial temperature range
and is supplied in a 32 lead plastic metric quad flatpack
(MQFP) package.
