a
10-Bit High Speed Multiplying D/A Converter
(Universal Digital Logic Interface)
DAC10*
All DAC10 series models guarantee full 10-bit monotonicity,
and nonlinearities as tight as +0.05% over the entire operating
temperature range are available. Device performance is essen-
tially unchanged over the
±
18 V power supply range, with
85 mW power consumption attainable at lower supplies.
A highly stable, unique trim method is used, which selectively
shorts Zener diodes, to provide 1/2 LSB full-scale accuracy
without the need for laser trimming.
Single-chip reliability, coupled with low cost and outstanding
flexibility, make the DAC10 device an ideal building block for
A/D converters, Data Acquisition systems, CRT displays, pro-
grammable test equipment and other applications where low
power consumption, input/output versatility and long-term
stability are required.
FEATURES
Fast Settling: 85 ns
Low Full-Scale Drift: 10 ppm/ C
Nonlinearity to 0.05% Max Over Temperature Range
Complementary Current Outputs: 0 mA to 4 mA
Wide Range Multiplying Capability: 1 MHz Bandwidth
Wide Power Supply Range: +5, –7.5 Min to 18 V Max
Direct Interface to TTL, CMOS, ECL, PMOS, NMOS
Availability in Die Form
GENERAL DESCRIPTION
The DAC10 series of 10-bit monolithic multiplying digital-to-
analog converters provide high speed performance and full-scale
accuracy.
Advanced circuit design achieves 85 ns settling times with very
low “glitch” energy and low power consumption. Direct inter-
face to all popular logic families with full noise immunity is
provided by the high swing, adjustable threshold logic inputs.
