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-

Rev. C

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 nonlineari-

ties 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, LCD display drivers, high speed modems, and other

applications where low cost, high speed, and complete

input/output versatility are required.
