ADA4096-4ARUZ

Overview

The ADA4096-4ARUZ 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. Key electrical specifications 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. The device incorporates overvoltage protection allowing inputs to extend 32 V beyond the rails without phase reversal.

Feature Summary

• Rail-to-rail input and output capability for maximum dynamic range
• Input overvoltage protection up to 32 V beyond supply rails
• No phase reversal during overvoltage conditions
• Micropower consumption suitable for battery-powered applications

Applications

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

Procurement Notes

Verify the specific package type matches the design requirements, as the ARUZ suffix indicates a 14-lead TSSOP package. Confirm that the operating temperature range of -40°C to +125°C aligns with the application environment. Ensure that the supply voltage limits do not exceed the absolute maximum ratings defined in the datasheet to prevent permanent damage.

Selection Notes

Select this component when high precision is required alongside low power consumption in portable devices. The rail-to-rail I/O feature makes it suitable for single-supply designs where signal swing must utilize the full supply range. Consider the 300 µV maximum offset voltage for applications requiring minimal DC error correction.

Part Context

This part belongs to the ADA4096 family of 30 V micropower amplifiers. It is functionally similar to the ADA4096-2 but contains four independent channels instead of two. The quad configuration allows for complex signal conditioning circuits within a compact footprint, reducing board space compared to using multiple dual-channel units.

FAQ

Does the ADA4096-4 experience phase reversal if the input voltage exceeds the supply rails?

No, the device features overvoltage protection that prevents phase reversal even when input voltages extend up to 32 V beyond the power supply rails.

What is the maximum supply voltage for the ADA4096-4ARUZ?

The maximum supply voltage is 30 V for single-supply operation or ±15 V for dual-supply operation.
