ADA4091-4ACPZ-R2

Overview

The ADA4091-4ACPZ-R2 is a quad micropower operational amplifier featuring rail-to-rail input and output capabilities. It operates from a single supply of 3.0 V to 30 V or dual supplies of ±1.5 V to ±15 V. Key electrical parameters include a gain bandwidth product of 1.27 MHz, a slew rate of 0.46 V/µs, and a maximum offset voltage of 400 µV in the LFCSP package. The device draws 200 µA per amplifier and includes overvoltage protection allowing inputs to exceed supply rails without phase reversal.

Feature Summary

• Features integrated overvoltage protection circuitry that allows input voltages to safely exceed supply rails without causing phase reversal or latch-up.
• Provides rail-to-rail signal swing at both the input and output stages to maximize dynamic range in low-voltage systems.
• Utilizes a unique input stage architecture combining PNP and NPN differential pairs for wide common-mode voltage coverage.

Applications

• Industrial process control
• Battery-powered instrumentation
• Power supply control and protection
• Remote sensors

Procurement Notes

Verify the specific package type and tape-and-reel quantity against the official Analog Devices ordering guide. Confirm that the component meets the required temperature range specifications for your application environment. Ensure compatibility with your PCB footprint dimensions before finalizing procurement decisions.

Selection Notes

Select this component when high precision is required alongside low power consumption in single-supply environments. The quad configuration reduces board space compared to individual dual amplifiers. Consider the thermal resistance characteristics if multiple channels are driven near their limits simultaneously.

Part Context

This part belongs to the ADA4091 family of low-power, 36 V operational amplifiers manufactured by Analog Devices. It serves as the quad-channel variant within a lineup that also includes dual-channel versions and other precision amplifier families designed for industrial and portable applications.

Replacement Considerations

Direct functional substitutes within the same family include the ADA4091-2 series for dual-channel requirements. Verify pinout compatibility and electrical specifications against the manufacturer's cross-reference documentation before implementing any alternative components.
