ADA4097-2HRZ

Overview

The ADA4097-2HRZ is a dual-channel, precision operational amplifier manufactured by Analog Devices Inc. It features Over-The-Top input capability with an ultrawide common-mode range extending to +70 V relative to the negative supply. The device operates on a single supply from +3 V to +50 V or split supplies up to ±25 V. Key electrical specifications include a gain-bandwidth product of 130 kHz, a typical supply current of 32.5 µA per channel, and a maximum input offset voltage of ±60 µV. It supports a wide operating temperature range from -55°C to +150°C.

Feature Summary

• Over-The-Top input architecture allows operation beyond the positive supply rail up to +70 V without phase reversal.
• Robust design includes high electrostatic discharge protection ratings for harsh industrial environments.
• Low power consumption with integrated shutdown functionality to minimize energy usage during idle periods.
• High precision performance characterized by low input offset voltage and drift across extended temperature ranges.

Applications

• Industrial sensor signal conditioning
• Supply current sensing in battery management systems
• Power supply monitoring circuits
• Front-end amplifiers in abusive electrical environments

Procurement Notes

Verify the specific grade (B or H) and package configuration when sourcing, as the HRZ suffix indicates the H-grade variant in LFCSP packaging. Confirm availability through authorized distributors, as lead times may vary due to manufacturing constraints. Ensure ESD precautions are strictly followed during handling and assembly to prevent damage to the sensitive input stages.

Selection Notes

Select this component for applications requiring high-voltage input sensing where standard op amps would fail. The H-grade rating ensures reliability in extreme thermal conditions exceeding standard industrial limits. Consider the shutdown feature if power conservation is critical. Verify that the 130 kHz bandwidth meets the signal frequency requirements for the intended application.

Part Context

This part belongs to the ADA4097 family of robust, precision operational amplifiers designed for demanding industrial applications. The dual-channel version provides two independent amplifiers in a compact footprint. The family shares core architectural features including Over-The-Top inputs and low quiescent current, differing primarily in channel count and package options.

Replacement Considerations

Direct replacements within the same family include the ADA4097-1HRZ for single-channel applications. Other variants like the ADA4097-2ARZ or ADA4097-2BRZ offer similar electrical characteristics but differ in operating temperature range and package type. Verify pin compatibility and thermal performance before substituting.
