ADA4062-2BRZ-R7

Overview

The ADA4062-2BRZ-R7 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 minimal drift
• Unity-gain stable operation with rail-to-rail input capability near the positive supply
• Low power consumption suitable for battery-operated systems

Applications

• High-side signal conditioning and current sensing
• Micropower instrumentation amplifiers
• Active filters and notch filters
• Data acquisition systems
• Industrial process controls

Procurement Notes

Verify the B grade designation ensures the specified 1.5 mV maximum offset voltage limit. Confirm the -R7 suffix indicates tape and reel packaging rather than tube. Ensure the component matches the lead-free RoHS compliance standard. Check that the operating temperature range meets the required industrial specifications of -40°C to +125°C.

Selection Notes

Select this model when low input bias current and high input impedance are critical requirements. The B grade offers tighter offset voltage tolerances compared to the A grade. Consider the 8-lead SOIC package for standard surface-mount assembly processes. Evaluate the 165 μA supply current against system power budgets for portable applications.

Part Context
