ADA4084-1ARZ-R7

Overview

The ADA4084-1ARZ-R7 is a single-channel operational amplifier from Analog Devices, housed in an 8-lead SOIC package. It operates on supply voltages ranging from +3 V to +30 V (or ±1.5 V to ±15 V). Key electrical specifications include a maximum input offset voltage of 100 µV and a typical supply current of 625 µA per amplifier at ±15 V. The device features a gain bandwidth product of 15.9 MHz, a slew rate of 4.6 V/µs, and a voltage noise density of 3.9 nV/√Hz at 1 kHz. It supports industrial operating temperatures from -40°C to +125°C.

Feature Summary

Rail-to-rail input and output capability for maximizing dynamic range in single-supply systems.
Low power consumption with a typical supply current of 0.625 mA per amplifier.
High precision performance characterized by low offset voltage and low noise density.
Unity-gain stable operation suitable for direct feedback configurations.

Applications

Battery-powered instrumentation
High-side and low-side sensing
Power supply control and protection
Telecommunications equipment
ADC input buffers

Procurement Notes

Verify the specific ordering suffix R7 corresponds to reel packaging when sourcing. Confirm the SOIC-8 package variant matches the design footprint. Ensure the component meets RoHS compliance requirements for the target assembly process. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component for applications requiring rail-to-rail signal handling with low power constraints. The 100 µV maximum offset voltage makes it suitable for precision DC measurements. The 15.9 MHz bandwidth supports moderate-speed signal processing tasks. Consider the 8-lead SOIC package for standard surface-mount assembly workflows.

Part Context

This device belongs to the ADA4084 series, which includes dual and quad variants. The series is designed for high-voltage, low-noise applications. It complements other Analog Devices precision amplifiers like the AD867x series but offers rail-to-rail I/O capabilities not present in all family members.
