GENERAL DESCRIPTION
The DAC08 series of 8-bit monolithic digital-to-analog convert-
ers provide very high-speed performance coupled with low cost
and outstanding applications flexibility.
Advanced circuit design achieves 85 ns settling times with very
low “glitch” energy and at low power consumption. Monotonic
multiplying performance is attained over a wide 20-to-1 reference
current range. Matching to within 1 LSB between reference and
full-scale currents eliminates the need for full-scale trimming in
most applications. Direct interface to all popular logic families
with full noise immunity is provided by the high swing, adjust-
able threshold logic input.
High voltage compliance complementary current outputs are
provided, increasing versatility and enabling differential opera-
tion to effectively double the peak-to-peak output swing. In
many applications, the outputs can be directly converted to
voltage without the need for an external op amp.
All DAC08 series models guarantee full 8-bit monotonicity,
and nonlinearities as tight as ± 0.1% over the entire operating
temperature range are available. Device performance is essen-
tially unchanged over the ± 4.5 V to ± 18 V power supply range,
with 33 mW power consumption attainable at ± 5 V supplies.
The compact size and low power consumption make the DAC08
attractive for portable and military/aerospace applications;
devices processed to MIL-STD-883, Level B are available.
DAC08 applications include 8-bit, 1 µs A/D converters, servo
motor and pen drivers, waveform generators, audio encoders
and attenuators, analog meter drivers, programmable power
supplies, CRT display drivers, high-speed modems and other
applications where low cost, high speed and complete input/
output versatility are required.
