OP481GS

Instrumentation, Op Amps, Buffer Amps Overview

The OP481GS is a quad operational amplifier manufactured by Analog Devices Inc., housed in a 14-lead SOIC package. It features rail-to-rail output capability and operates on supply voltages ranging from 2.7 V to 12 V. Key electrical parameters include a gain-bandwidth product of 105 kHz, a slew rate of 27 mV/us, an input offset voltage of 1.5 mV, and an input bias current of 10 nA. The device draws a typical operating supply current of 16 uA per channel and exhibits an input voltage noise density of 75 nV/sqrt Hz. It functions within a temperature range of -40 C to +85 C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix (e.g., REEL7) against the required packaging format. Confirm RoHS compliance status through official documentation. Ensure the SOIC-14 footprint matches the target PCB layout. Validate that the operating temperature range meets environmental requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low quiescent current and rail-to-rail output are required. Compare input offset voltage and bias current against application sensitivity needs. Verify that the 105 kHz bandwidth suffices for the signal frequency. Check package availability and lead times with authorized distributors.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OP481 series of quad operational amplifiers from Analog Devices. It shares architectural similarities with other members of the family but differs in specific performance metrics like bandwidth and noise. The GS designation indicates the SOIC-14 surface-mount package variant.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult official substitution guides for compatible quad op-amps with similar rail-to-rail outputs and low power characteristics. Verify pin compatibility and electrical parameter overlaps before replacing.
