GENERAL DESCRIPTION
The OP420 quad micropower operational amplifier is a single-
chip 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 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.
