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 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.
