GENERAL DESCRIPTION
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.
