OP184FS

Instrumentation, Op Amps, Buffer Amps Overview

The OP184FS is a single-channel precision operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities, ensuring full signal swing across the supply range. The device operates on a single supply voltage from 3V to 36V or dual supplies from ±1.5V to ±18V. Key electrical specifications include a gain-bandwidth product of 4.25 MHz, a slew rate of 2.4 V/us, an input offset voltage of 175 uV, and an input bias current of 450 nA. It delivers an output current of 10 mA per channel with a typical input voltage noise density of 3.9 nV/sqrt Hz. Common-mode rejection ratio and power supply rejection ratio are both rated at 90 dB. The component is housed in an SOIC-8 surface-mount package and functions within a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix FS against the required datasheet revision, as it denotes the SOIC-8 tube packaging variant. Confirm that the component status aligns with project lifecycle requirements, as availability may be restricted. Ensure the operating temperature range meets environmental specifications. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when rail-to-rail I/O is required alongside precision DC characteristics in a single-supply environment. It is suitable for applications demanding high CMRR and PSRR without the need for negative supply rails. Consider the SOIC-8 package constraints for thermal management and PCB layout. Evaluate the 4.25 MHz bandwidth against signal frequency requirements to ensure adequate phase margin and stability in feedback configurations.

Instrumentation, Op Amps, Buffer Amps Part Context

The OP184FS belongs to the OP184 series of precision amplifiers from Analog Devices. This series is characterized by its combination of wide bandwidth and low noise, making it distinct from slower, higher-precision devices. The FS suffix specifically identifies the plastic small outline package variant. It serves as a bridge between general-purpose op-amps and specialized instrumentation amplifiers, offering versatility in mixed-signal designs.
