ADA4062-4ACPZ-R7

Overview

The ADA4062-4ACPZ-R7 is a quad JFET-input operational amplifier manufactured by Analog Devices. It operates within a supply voltage range of ±5 V to ±15 V and supports an extended industrial temperature range from -40°C to +125°C. Key electrical specifications include a typical gain-bandwidth product of 1.4 MHz, a slew rate of 3.3 V/μs, and a maximum input bias current of 50 pA. The device features a maximum offset voltage of 2.5 mV and consumes 165 μA per amplifier. It is housed in a 16-lead LFCSP package.

Feature Summary

• JFET input architecture providing ultralow bias current and high input impedance
• Low power consumption suitable for energy-efficient designs
• Unity-gain stable with industry-leading low offset voltage and drift
• Extended industrial operating temperature range

Applications

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

Procurement Notes

Verify the specific grade (A or B) and package option when sourcing, as performance parameters like offset voltage vary between grades. Confirm that the R7 suffix indicates reel packaging. Ensure compatibility with the required supply voltage range and thermal management needs for the 16-lead LFCSP package during integration.

Selection Notes

Select this component for applications requiring low noise and high input impedance without rail-to-rail output requirements. Consider the A grade specification for offset voltage limits if precision is critical. Evaluate the 16-lead LFCSP footprint against available board space and thermal dissipation capabilities for the target environment.

Part Context

This part belongs to the ADA4062 family of low-power JFET-input amplifiers. The quad configuration integrates four independent amplifiers into a single package, offering channel separation of 130 dB at 1 kHz. It serves as a cost-effective solution for multi-channel signal conditioning compared to using discrete dual amplifiers.

FAQ

Does the ADA4062-4 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. Phase reversal occurs only if inputs are driven beyond the negative supply limit.

What is the input common-mode voltage range?

The input common-mode voltage range extends from the negative supply rail plus 0.5 V up to the positive supply rail.
