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.
*Protected by Patent Nos. 4,055,770, 4,056,740 and 4,092,639.

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-

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.
