1 / 8 page MP7614 1 Rev. 2.00 FEATURES • Full Four-Quadrant Multiplication • Excellent Stability Over Temperature and Time • Guaranteed Monotonic • TTL/5 V CMOS Compatible 15 V CMOS Multiplying 14-Bit Digital-to-Analog Converter • Low Sensitivity to Output Amplifier VOS • Low Glitch Energy • 16-Bit Version: MP7616 GENERAL DESCRIPTION The MP7614 is a high density 14-bit CMOS multiplying Digi- tal-to-Analog Converter. Silicon nitride passivation and un- trimmed silicon chromium resistors have been combined to pro- vide long term stability and reliability. Using the most significant bit (MSB) segmentation technique, the MP7614 features 13-bit (0.012%) differential and 12-bit (0.01%) integral linearity. To achieve 13-bit linearity without laser trim, the MP7614 digi- tally decodes the four MSB’s into 15 equal current sources, rather than the standard binary-weighted sources. Each resis- tor contributes only 1/16 full scale output thus reducing the matching accuracy requirement of the resistor and CMOS switches from 0.0015% to 0.006%. The decoding technique achieves an eightfold improvement in differential linearity stability over temperature, an eightfold im- provement in relative accuracy due to aging effects (long term stability), a fourfold improvement in glitch amplitude, and a ten- fold reduction in sensitivity to output amplifier offset voltage.
