ADA4091-4ACPZ-R7

Overview

The ADA4091-4ACPZ-R7 is a quad precision operational amplifier from Analog Devices, featuring rail-to-rail input and output capabilities. It operates on single supplies from 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 250 µV at ±15 V. The device incorporates overvoltage protection (OVP) allowing inputs to exceed supply rails safely without phase reversal. It draws 200 µA per amplifier and functions within an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Features integrated overvoltage protection that allows input voltages to exceed supply rails safely without causing phase reversal or latch-up.
• Provides rail-to-rail input and output swing capability, enabling full signal utilization in single-supply systems.
• Delivers micropower performance with low supply current consumption while maintaining high bandwidth for precision applications.

Applications

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

Procurement Notes

Verify the specific package variant and reel specifications against the manufacturer's ordering guide before procurement. Confirm that the component meets RoHS compliance requirements for your region. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference the datasheet revision to confirm parameter stability. Validate that the intended operating conditions align with the absolute maximum ratings provided in the official documentation.

Selection Notes

Select this component when designing circuits requiring both high precision and wide dynamic range in a single-supply environment. The integrated overvoltage protection simplifies design efforts for transducer interfaces where input signals may exceed supply limits. Consider the low power consumption suitable for battery-operated devices. Evaluate the thermal resistance characteristics if operating near the upper temperature limit. Ensure the required bandwidth and slew rate meet the signal processing demands of the application.

Part Context

This part belongs to the ADA4091 family of low-power, 36 V operational amplifiers manufactured by Analog Devices. The quad configuration offers four independent amplifiers in a single package, reducing board space compared to dual versions. It complements other series members like the ADA4091-2 and provides a solution for applications needing multiple precision channels with robust input protection features.
