ADA4062-2BRZ

Overview

The ADA4062-2BRZ is a dual JFET-input operational amplifier in an 8-lead SOIC package. It features a maximum offset voltage of 1.5 mV and a typical 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, a gain bandwidth product of 1.4 MHz, and a common-mode rejection ratio of 90 dB. Input bias current is typically 2 pA, with a maximum of 50 pA.

Feature Summary

• JFET input stage providing ultralow bias current and high input impedance
• B grade specification for low offset voltage and drift
• Unity-gain stable operation without phase reversal within specified common-mode range
• Low power consumption suitable for battery-operated instrumentation

Applications

• Power controls and monitoring
• Active filters
• Industrial and process controls
• Data acquisition systems
• Input buffering

Procurement Notes

Verify the specific B grade designation ensures compliance with the 1.5 mV maximum offset voltage requirement. Confirm the 8-lead SOIC package matches the footprint constraints. Ensure the operating temperature range covers the intended application environment. Check RoHS compliance status if required by manufacturing standards.

Selection Notes

Select this component when low bias current and low offset voltage are critical. The B grade offers tighter offset specifications than the A grade. Consider the 1.4 MHz bandwidth for signal conditioning applications. Verify that the ±5 V to ±15 V supply range fits the system design. Evaluate thermal resistance for heat dissipation requirements.

Part Context

This part 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 precise DC performance. The device is designed for industrial and instrumentation environments.

Replacement Considerations

ADA4062-2ARZ provides similar functionality but with A grade offset specifications. ADA4062-2ARMZ offers the same B grade performance in an MSOP package. Verify pin compatibility and electrical parameter differences before substitution.

FAQ

Does the ADA4062-2 experience phase reversal?

The output does not phase reverse if inputs exceed the common-mode range but remain within the positive supply rail and 0.5 V above the negative supply rail.

What is the input bias current specification?

The typical input bias current is 2 pA, with a maximum of 50 pA at 25°C.
