GENERAL DESCRIPTION

The DAC08 series of 8-bit monolithic digital-to-analog convert­ers 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 refer-

(Universal Digital Logic Interface)

DAC08

ence 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, adjustable threshold logic input.

High voltage compliance complementary current outputs are
provided, increasing versatility and enabling differential opera­tion 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 essentially
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.
