ADA4098-2BRZ

Overview

The ADA4098-2BRZ 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 −VS + 70 V and a supply voltage range of +3 V to +50 V. Key electrical parameters include a gain-bandwidth product of 1.05 MHz, a slew rate of 0.85 V/µs, and a maximum input offset voltage of ±35 µV (B grade). The device consumes 165 µA per channel, offers low noise density of 17 nV/√Hz, and supports shutdown functionality.

Feature Summary

• Robust Over-The-Top input stage tolerant to high differential voltages without phase reversal
• Low power consumption with dedicated shutdown mode for energy efficiency
• High precision DC performance characterized by minimal offset voltage and drift
• Integrated electrostatic discharge protection for enhanced durability

Applications

• Industrial sensor signal conditioning
• Supply current sensing
• Battery and power supply monitoring
• Front-end amplifiers in abusive environments
• 4 mA to 20 mA transmitters

Procurement Notes

Verify the specific B-grade classification and BRZ package suffix against the manufacturer's official ordering guide to ensure compatibility with design requirements. Confirm availability status through authorized distributors as supply levels may fluctuate. Ensure proper ESD handling procedures are followed during storage and assembly to maintain component integrity.

Selection Notes

Select this component for applications requiring high-voltage tolerance and precision in single-supply systems. The dual-channel configuration reduces board space compared to single units. Consider the thermal resistance characteristics when designing PCB layouts for high ambient temperatures or heavy load driving conditions.

Part Context

This part belongs to the ADA4098 family of robust, precision op amps designed for demanding industrial environments. The dual-channel variant provides two independent amplifiers in one package, sharing a common power supply and ground reference while maintaining individual signal paths for efficient system integration.

Replacement Considerations

Consult the manufacturer's documentation for verified substitute part numbers within the same series or equivalent specifications.
