ADA4062-4ARUZ-RL

Overview

The ADA4062-4ARUZ-RL is a quad JFET-input operational amplifier manufactured by Analog Devices Inc. It operates on dual supplies ranging from ±5 V to ±15 V and functions within an extended industrial temperature range of −40°C to +125°C. Key electrical specifications include a maximum input bias current of 50 pA, a typical supply current of 165 μA per amplifier, and a gain-bandwidth product of 1.4 MHz. The device features a typical slew rate of 3.3 V/μs, an offset voltage of 2.5 mV (A grade), and a common-mode rejection ratio of 90 dB. It is housed in a 14-lead TSSOP package.

Feature Summary

• JFET input architecture providing ultralow bias current and high input impedance
• Low power consumption with minimal supply current requirements
• Extended industrial operating temperature range for harsh environments
• Unity-gain stable design suitable for direct feedback configurations

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 A-grade offset voltage limits and thermal resistance values against the official datasheet before finalizing designs. Confirm that the 14-lead TSSOP package dimensions match the target PCB footprint. Ensure supply sequencing rules are followed to prevent phase reversal or damage during startup conditions.

Selection Notes

Select this component when low input bias current and high input impedance are critical for signal integrity. The quad configuration reduces board space compared to individual dual amplifiers. Verify that the required bandwidth and slew rate meet the dynamic performance needs of the application circuit.

Part Context

This part belongs to the ADA4062 family of low-power JFET-input amplifiers. The quad variant integrates four independent amplifiers into a single package. It shares core electrical characteristics with the dual ADA4062-2 but offers higher channel density. The family is designed for applications requiring precision and low power consumption simultaneously.

Replacement Considerations

ADA4062-4ACPZ-R7 is a compatible quad variant available in a 16-lead LFCSP package.
