The OP420 quad micropower operational amplifier is a singlechip quad patterned after the OP20 precision micropower single
operational amplifier. 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.

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.
