GENERAL DESCRIPTION The OP-420 quad micropower operational amplifier is a single-chip quad patterned after the OP-2C) precision micro- power 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 SIMPLIFIED SCHEMATIC (1/4 Shown) Quad Micropower Operational Amplifier OP-420 (~40jiA/section at 5V), provides a unique solution for designs requiring high functional density and portable operation. Applications include two-wire transmitters for process control loops, battery-operated remote-line filters, signal preconditioning amplifiers, and a variety of multiple-gain block arrays. For micropower applications requiring offset nulling, seethe OP-2C), OP-21 and OP-22 data sheets.
