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 interface to all popular logic families with full noise immunity is provided by the high swing, adjustable threshold logic inputs.

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.
