ADA4098-2BRZ-RL7

Overview

The ADA4098-2BRZ-RL7 is a dual-channel precision operational amplifier manufactured by Analog Devices Inc. It features an ultrawide common-mode input range from −VS − 0.1 V to −VS + 70 V and supports power supply voltages between +3 V and +50 V. The device offers a gain-bandwidth product of 1.05 MHz, a slew rate of 0.85 V/µs, and low input offset voltage of ±35 µV maximum. Each channel consumes 165 µA typical supply current and includes shutdown functionality with a maximum current of 20 µA.

Feature Summary

• Over-The-Top input capability allowing operation up to 70 V above the negative supply rail
• Robust input protection against differential overdrive without phase reversal
• Low quiescent power consumption with dedicated low-power shutdown mode
• High precision DC performance characterized by low offset voltage and drift

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 RL7 reel packaging suffix against the manufacturer's official ordering guide. Confirm that the component meets the required temperature range specifications for the intended application environment before finalizing procurement.

Selection Notes

Select this component when high-voltage common-mode signals require amplification beyond standard supply rails. The dual-channel configuration provides cost-effective precision for applications needing two independent Over-The-Top inputs within a single package footprint.

Part Context

This part belongs to the ADA4098 family of robust, precision operational amplifiers designed for demanding industrial environments. The dual-channel variant integrates two identical amplifier circuits into one package, sharing common power and ground connections while maintaining independent signal paths.

Replacement Considerations

Consult the manufacturer's related products section for verified substitutes such as the ADA4098-1 or other packages within the same series.
