GENERAL DESCRIPTION
The DAC10 series of 10-bit monolithic multiplying digital-toanalog 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 interface to all popular logic families with full noise immunity is
provided by the high swing, adjustable threshold logic inputs.
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 essentially 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, programmable test equipment and other applications where low
power consumption, input/output versatility and long-term
stability are required.
