ADA4096-4ARUZ-R7

Overview

The ADA4096-4ARUZ-R7 is a quad operational amplifier from Analog Devices featuring micropower operation and rail-to-rail input/output swing. It operates on single supplies from 3 V to 30 V or dual supplies of ±1.5 V to ±15 V. The device includes overvoltage protection allowing inputs up to 32 V beyond the rails without phase reversal. Key electrical parameters include a maximum offset voltage of 300 µV, a typical unity-gain bandwidth of 800 kHz at ±15 V, and a supply current of approximately 60 µA per amplifier.

Feature Summary

• Integrated overvoltage protection allows safe input voltages extending 32 V above and below the supply rails without phase reversal or latch-up.
• Rail-to-rail input and output capability ensures maximum dynamic range for low-voltage applications.
• Micropower architecture provides typical quiescent current of 60 µA per amplifier for extended battery life.
• Low noise density of 27 nV/√Hz supports high-fidelity signal conditioning in portable audio systems.

Applications

• Battery monitoring systems
• Sensor conditioners
• Portable power supply controls
• Portable instrumentation

Procurement Notes

Verify the specific ordering suffix R7 corresponds to the reel packaging configuration required for your assembly line. Confirm that the ARUZ variant matches the 14-lead TSSOP footprint and thermal requirements of your PCB design. Ensure compatibility with the -40°C to +125°C operating temperature range specified for industrial environments.

Selection Notes

Select this component when designing circuits requiring four independent amplifiers within a compact surface-mount package. It is suitable for applications demanding low power consumption alongside robust input protection against transient overvoltages. Consider the 14-lead TSSOP form factor if space constraints preclude larger packages while maintaining thermal performance.

Part Context

This part belongs to the ADA4096 family of precision amplifiers designed for portable and battery-powered electronics. The quad configuration consolidates multiple channels into a single package, reducing board space compared to discrete solutions. It complements the dual-channel ADA4096-2 variant, offering higher integration density for complex signal processing tasks.
