ADA4096-2ARMZ-R7

Overview

The ADA4096-2ARMZ-R7 is a dual-channel precision operational amplifier manufactured by Analog Devices Inc. It features micropower operation with a typical supply current of 60 µA per amplifier and supports single-supply voltages from 3 V to 30 V. The device provides rail-to-rail input and output swing, ensuring maximum dynamic range. Key electrical specifications include a gain-bandwidth product of 800 kHz at ±15 V, an input offset voltage of 300 µV maximum, and a voltage noise density of 27 nV/√Hz. It incorporates overvoltage protection allowing inputs to extend 32 V beyond the supply rails without phase reversal.

Feature Summary

• Features input overvoltage protection that allows signal voltages to exceed supply rails by up to 32 V without causing phase reversal or latch-up.
• Provides rail-to-rail input and output capability, maximizing dynamic range in low-voltage applications.
• Delivers micropower consumption with a typical supply current of 60 µA per amplifier for battery-operated systems.
• Ensures stable operation with unity-gain stability and handles capacitive loads up to 200 pF without oscillation.

Applications

• Battery monitoring and management systems
• Sensor conditioners for industrial and portable instrumentation
• Portable power supply controls
• Battery-powered audio applications

Procurement Notes

Verify the specific ordering suffix R7 corresponds to tape-and-reel packaging when sourcing this component. Confirm package availability matches the required MSOP-8 form factor. Check manufacturer documentation for automotive qualification status if applicable to your design requirements.

Selection Notes

Select this component for designs requiring high precision with minimal power consumption. The wide common-mode input range and rail-to-rail output are suitable for single-supply systems. Ensure the load capacitance does not exceed 200 pF to maintain stability without additional compensation components.
