ADA4062-2BRZ-RL

Overview

The ADA4062-2BRZ-RL is a dual JFET-input operational amplifier in an 8-lead SOIC package. It features a maximum offset voltage of 1.5 mV and drift of 5 μV/°C. The device 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 slew rate of 3.3 V/μs, gain bandwidth product of 1.4 MHz, and input bias current of 50 pA maximum.

Feature Summary

• JFET input stage providing ultralow bias current and high input impedance
• B grade specification for low offset voltage and minimal drift
• Unity-gain stable design suitable for direct feedback configurations
• Low power consumption optimized for battery-operated systems

Applications

• Power controls and monitoring circuits
• Active filter implementations
• Industrial and process control instrumentation
• Data acquisition signal conditioning
• High-side signal sensing applications

Procurement Notes

Verify the B grade designation ensures compliance with the 1.5 mV maximum offset voltage requirement. Confirm the -RL suffix indicates tape and reel packaging for automated assembly processes. Ensure the component meets RoHS standards as indicated by the Z suffix in the ordering guide.

Selection Notes

Select this model when low offset voltage and drift are critical alongside low power consumption. The B grade offers tighter DC specifications than the A grade variant. Verify that the 8-lead SOIC package dimensions fit the target PCB layout constraints.

Part Context

This component belongs to the ADA4062 family of low-power JFET-input amplifiers. The family includes quad versions and various package options like MSOP and LFCSP. The B grade specifically targets applications requiring superior DC accuracy compared to standard precision amplifiers.

Replacement Considerations

ADA4062-2ARZ provides identical functionality with A grade specifications.
