ADA4062-2ARZ

Overview

The ADA4062-2ARZ is a dual JFET-input operational amplifier in an 8-lead SOIC package. It operates on dual supplies from ±5 V to ±15 V with a typical supply current of 165 μA per amplifier. Key electrical parameters include a maximum offset voltage of 2.5 mV, a typical slew rate of 3.3 V/μs, and a gain bandwidth product of 1.4 MHz. The device features a maximum input bias current of 50 pA and a typical common-mode rejection ratio of 90 dB.

Feature Summary

• JFET input stage providing ultralow bias current and high input impedance
• Low power consumption suitable for battery-operated applications
• Unity-gain stable operation without external compensation components
• Extended industrial temperature range capability

Applications

• Power controls and monitoring systems
• Active filter implementations
• Industrial and process control instrumentation
• Data acquisition signal conditioning
• Input buffering stages

Procurement Notes

Verify the specific grade (A or B) required for your application, as the standard suffix indicates A grade performance. Confirm that the 8-lead SOIC package option matches your PCB footprint requirements. Ensure the ordering suffix aligns with your preferred packaging format, such as tube or reel, before finalizing procurement orders.

Selection Notes

Select this component when low input bias current and high input impedance are critical design constraints. The dual-channel configuration allows for cost-effective implementation of differential circuits within a single package. Consider the extended temperature range if the operating environment exceeds standard commercial limits.

Part Context

This part belongs to the ADA4062 family of low-power JFET-input amplifiers manufactured by Analog Devices. The family includes quad variants and alternative packages like MSOP and LFCSP. The device is designed to offer industry-leading performance metrics regarding offset voltage and drift while maintaining low power consumption.

Replacement Considerations

ADA4062-2ARMZ provides the same functionality in an 8-lead MSOP package.
