A Darlington PNP input stage allows the input common-mode voltage to include V–. The wide input range combined with low power supply drain (~40 µA/section at

5 V) provides a unique solution for designs requiring high func-

tional density and portable operation. Applications include 2-wire transmitters for process control loops, battery-operated remote-line filters, signal preconditioning amplifiers, and a variety of multiple-gain block arrays. –IN –IN Q3 Q4 Q11 Q10 Q13 Q12 Q33 Q26 Q27 Q29 OUTPUT Q28 Figure 1.

*Not for new design; obsolete April 2002. ABSOLUTE MAXIMUM RATINGS 1 Operating Temperature Range Junction Temperature (T CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the OP420 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. WARNING!
