FEATURES Low Supply Current: 200 A Max @ VS = 5 V Single-Supply Operation: 5 V to 30 V Dual-Supply Operation: 2.5 V to 15 V Low Input Offset Voltage: 500 V Typ Low Input Offset Voltage Drift: 5 V/؇C Typ High Common-Mode Input Range: V– to (V+ – 1.5 V) High CMRR: 100 dB Typ High Open-Loop Gain: 1100 V/mV Typ LM 148 Pinout
GENERAL DESCRIPTION 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.
