OP484FP

Instrumentation, Op Amps, Buffer Amps Overview

The OP484FP is a quad precision operational amplifier manufactured by Analog Devices Inc., featuring rail-to-rail input and output capabilities. It operates within a supply voltage range of 3 V to 36 V or dual supplies of ±1.5 V to ±18 V. The device offers a gain-bandwidth product of 4.25 MHz and a slew rate of 2.4 V/µs. Key electrical specifications include an input offset voltage of 150 µV, input bias current of 450 nA, and input voltage noise density of 3.9 nV/√Hz. It provides a common-mode rejection ratio of 90 dB and delivers 10 mA per channel output current while consuming 5.8 mA of operating supply current. The component is housed in a 14-lead SOIC package and supports surface mount installation.
