ADA4062-2ARZ-RL

Overview

The ADA4062-2ARZ-RL is a dual JFET-input operational amplifier in an 8-lead SOIC package. It features a typical supply current of 165 μA per amplifier, a gain bandwidth product of 1.4 MHz, and a slew rate of 3.3 V/μs. The device operates on dual supplies ranging from ±5 V to ±15 V. Input characteristics include a maximum offset voltage of 2.5 mV (A grade) and a typical input bias current of 2 pA. It maintains operation within the extended industrial temperature range of −40°C to +125°C.

Feature Summary

• JFET input architecture providing ultralow bias current and high input impedance
• Low power consumption with typical supply current of 165 μA per amplifier
• Phase reversal immunity when inputs exceed common-mode range but remain within positive rail
• Unity-gain stable design suitable for buffering and active filtering

Applications

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

Procurement Notes

Verify that the ordering suffix -RL corresponds to reel packaging as specified in the manufacturer's ordering guide. Confirm the component grade matches application requirements, noting that A grade specifies a maximum offset voltage of 2.5 mV. Ensure the 8-lead SOIC package option aligns with PCB footprint constraints and thermal management needs for the target environment.

Selection Notes

Select this component for applications requiring low power dissipation combined with high input impedance. The JFET input stage minimizes loading effects on high-impedance signal sources. Consider the specific offset voltage drift and bias current specifications if precision over wide temperature ranges is critical. Verify that the single-supply or dual-supply configuration fits the system voltage rails.

Part Context

This part belongs to the ADA4062 family of low-power JFET-input amplifiers, which also includes quad configurations like the ADA4062-4. The family is designed for instrumentation and industrial equipment where low noise and low power are essential. The -2 designation indicates a dual-channel configuration housed in surface-mount packages such as SOIC, MSOP, and LFCSP.

FAQ

Does the ADA4062-2 exhibit phase reversal?

No, the output does not phase reverse if one or both inputs exceed the input voltage range but remain within the positive supply rail and 0.5 V above the negative supply rail.

What is the typical input bias current?

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