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 functional 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. 15 –IN D 14 +IN D V+ 4 N.C. 8 GENERAL DESCRIPTION + OP420CRC/883 20-Lead LCC (RC-Suffix) V+ Q11 Q3 –IN Q28 Q12 Q4 Q2 Q1 Q26 Q9 OUTPUT Q10 Q8 –IN Q27 Q7 C1 Q29 Q5 Q6 Q13 Q33 V– Figure 1.

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. –4– WARNING! ESD SENSITIVE DEVICE REV.
