FEATURES
Fast settling output current: 85 ns
Full-scale current prematched to ±1 LSB
Direct interface to TTL, CMOS, ECL, HTL, PMOS
Nonlinearity to 0.1% maximum over temperature range
High output impedance and compliance: −10 V to +18 V
Complementary current outputs
Wide range multiplying capability: 1 MHz bandwidth
Low FS current drift: ±10 ppm/°C
Wide power supply range: ±4.5 V to ±18 V
Low power consumption: 33 mW at ±5 V
Low cost
8-Bit, High Speed, Multiplying
D/A Converter
DAC08
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, LCD display drivers, high speed modems, and other
applications where low cost, high speed, and complete
input/output versatility are required.
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.
