MP7614

15 V CMOS

Multiplying 14-Bit

Digital-to-Analog Converter

FEATURES

• Full Four-Quadrant Multiplication

• Excellent Stability Over Temperature and Time

• Guaranteed Monotonic

• Low Sensitivity to Output Amplifier V

• Low Glitch Energy

• 16-Bit Version: MP7616

• TTL/5 V CMOS Compatible

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%.

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.

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.

To achieve 13-bit linearity without laser trim, the MP7614digi-

tally decodes the four MSB’s into 15 equal current sources,
