ADA4096-2ARMZ

Overview

The ADA4096-2ARMZ 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 in low-voltage applications. It incorporates overvoltage protection (OVP) that allows input voltages to extend 32 V beyond the supply rails without phase reversal or latch-up. Key electrical specifications include a maximum offset voltage of 300 µV, a voltage noise density of 27 nV/√Hz at 1 kHz, and a unity-gain bandwidth of approximately 800 kHz at ±15 V. The component is housed in an 8-lead MSOP package.

Feature Summary

• Input overvoltage protection allowing signals up to 32 V beyond supply rails without phase reversal
• Rail-to-rail input and output capability for extended dynamic range
• Micropower consumption suitable for battery-powered systems
• Low offset voltage and low noise characteristics for precision signal conditioning

Applications

• Battery monitoring and management systems
• Sensor signal conditioners
• Portable power supply controls
• Portable instrumentation devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel versus tube packaging configurations. Ensure the selected variant matches the required automotive qualification status if applicable to the design environment. Cross-reference the datasheet revision to confirm all electrical parameters align with the intended operating conditions.

Selection Notes

Select this component when designing circuits requiring high precision under low-power constraints. The rail-to-rail I/O makes it suitable for single-supply systems where maximizing signal swing is critical. The integrated overvoltage protection offers robustness in industrial environments prone to transient input errors. Consider the thermal resistance of the MSOP package for heat dissipation requirements in densely populated PCB layouts.

Part Context

This device belongs to the ADA409x family of low-power, 30 V operational amplifiers from Analog Devices. It complements other members like the ADA4091-2 and ADA4096-4 within the portfolio. The family targets applications demanding a balance between precision, power efficiency, and ruggedness. The dual configuration provides two independent channels in a compact footprint, simplifying board space allocation compared to single-channel alternatives.

Replacement Considerations

Check for ADA4096-2ARMZ-R7 and ADA4096-2ARMZ-RL as alternative packaging variants of the same functional device. Verify pin compatibility and electrical specifications before substituting with other op-amps in the ADA409x series.
