DAC-08 Series

8-bit high-speed multiplying D/A converter

2001 Aug 03

853-0045 26832

DESCRIPTION

The DAC-08 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 70 ns 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 DAC-08 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

±4.5 V

±18 V power supply range, with 37 mW power consumption

attainable at

±5 V supplies.

The compact size and low power consumption make the DAC-08

attractive for portable and military aerospace applications.
