Procurement Notes

Verify the specific package type and temperature range against project requirements before ordering. Confirm that the A-grade offset voltage specifications meet system accuracy needs. Ensure supply sequencing rules are followed during design to prevent damage. Check for RoHS compliance status if required by manufacturing standards.

Selection Notes

Select this component when low power and high input impedance are critical. The quad configuration reduces board space compared to individual amplifiers. Consider the TSSOP package dimensions for PCB layout constraints. Evaluate the 1.4 MHz bandwidth against signal frequency requirements to ensure adequate phase margin and stability.

Part Context

This part belongs to the ADA4062 family of low-power JFET-input op amps. The family includes dual and quad variants available in various packages like SOIC, MSOP, and LFCSP. The quad version consolidates four amplifiers into a single compact footprint, ideal for multi-channel signal conditioning tasks requiring precision and low noise.

FAQ

Does the ADA4062-4ARUZ exhibit phase reversal?

No, 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 common-mode voltage range?

The input voltage range extends from −11.5 V to +15 V under standard operating conditions.
