OP184ESZ-REEL7

Instrumentation, Op Amps, Buffer Amps Overview

The OP184ESZ-REEL7 is a single-channel precision operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities, operating on a single supply voltage ranging from 3 V to 36 V (or ±1.5 V to ±18 V). Key electrical specifications include a gain-bandwidth product of 4.25 MHz, a slew rate of 2.4 V/µs, an input offset voltage of 65 µV, and an input bias current of 450 nA. The device draws 1.45 mA of quiescent current per channel and provides an output current of 10 mA. It is housed in an 8-pin SOIC package with a wide operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output functionality for maximum dynamic range in single-supply systems
• High slew rate and wide bandwidth suitable for demanding AC performance applications
• Low input offset voltage and low noise density for high-precision signal conditioning

Instrumentation, Op Amps, Buffer Amps Applications

• Noise circuit modeling to determine total circuit equivalent input noise voltage
• High-side load current monitoring circuits
• Buffering networks to compensate for capacitive loads
• Driving 12-bit DACs with 5V single-supply operation

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix REEL7 indicates tape-and-reel packaging when ordering. Confirm that the 8-pin SOIC package matches your PCB footprint requirements. Ensure the operating temperature range of -40°C to +125°C meets your environmental specifications. Cross-reference the pinout with the official Analog Devices datasheet before integration.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring both high-speed AC performance and precise DC accuracy in single-supply environments. The rail-to-rail I/O allows for full-scale signal swing near the supply rails. Consider the ADA4084-1 as a modern alternative if higher bandwidth or lower power consumption is required.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OP184 family, which includes dual (OP284) and quad (OP484) variants. All share similar electrical characteristics but differ in channel count and package options. The OP184 is designed for portable telecommunications, power control, and instrumentation where low noise and high precision are critical.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The ADA4084-1 is identified as a direct replacement option. It offers doubled bandwidth and halved power consumption compared to the OP184 series while maintaining similar precision characteristics.
