8-Bit high-speed multiplying D/A converter
Product specification
DAC08 Series
DESCRIPTION
The DAC08 series of 8-bit monolithic multiplying Digital-to-Analog
Converters provide very high-speed performance coupled with low
cost and outstanding applications flexibility.
Advanced circuit design achieves 70ns settling times with very low
glitch 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, adjustable threshold logic inputs.
Dual complementary outputs are provided, increasing versatility and
enabling differential operation to effectively double the peak-to-peak
output swing. True high voltage compliance outputs allow direct
output voltage conversion and eliminate output op amps in many
applications.
All DAC08 series models guarantee full 8-bit monotonicity and
linearities as tight as 0.1% over the entire operating temperature
range. Device performance is essentially unchanged over the ±4.5V
to ±18V power supply range, with 37mW power consumption
attainable at ±5V supplies.
The compact size and low power consumption make the DAC08
attractive for portable and military aerospace applications.
FEATURES
• Fast settling output current—70ns
• Full-scale current prematched to ±1 LSB

• Wide range multiplying capability
• Low FS current drift — ±10ppm/°C
• Wide power supply range—±4.5V to ±18V
• Low power consumption—37mW at ±5V
APPLICATIONS
• 8-bit, 1µs A-to-D converters
• Servo-motor and pen drivers
