DAC−08 SERIES
8−Bit High−Speed
Multiplying D/A Converter
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 to "18 V power supply range, with 37 mW power
consumption attainable at "5.0 V supplies.
The compact size and low power consumption make the DAC-08
attractive for portable and military aerospace applications.

Characteristics
NOTES:
B1 through B8 have identical transfer characteristics.
Bits are fully switched, with less than 1/2LSB error, at
less than ±100mV from actual threshold. These switching
points are guaranteed to lie between 0.8 and 2.0V over
the operating temperature range (VLC = 0.0V).
