ADA4098-1BUJZ-R5

Overview

The ADA4098-1BUJZ-R5 is a single-channel, precision operational amplifier manufactured by Analog Devices Inc. It features an Over-The-Top input stage allowing operation from −VS to +VS and beyond, with a maximum common-mode voltage of −VS + 70 V. The device operates on supply voltages ranging from +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 typical supply current of 165 µA per channel. It offers low input offset voltage (±35 µV max) and low noise (17 nV/√Hz). The component is housed in a 6-lead TSOT package.

Feature Summary

• Over-The-Top input capability enabling robust operation above the positive supply rail
• Low power consumption with shutdown functionality for extended battery life
• High precision DC performance with minimal offset voltage and drift
• Integrated input protection against overdrive and electrostatic discharge

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 temperature range and package configuration against the final design requirements. Confirm that the 6-lead TSOT footprint matches the PCB layout. Ensure ESD handling procedures are followed during assembly due to the sensitivity of the CMOS input stages. Cross-reference the ordering suffix with the manufacturer's latest documentation to confirm availability and revision status.

Selection Notes

Select this component when high DC accuracy is required alongside wide common-mode input ranges extending above the positive supply rail. It is suitable for applications demanding low quiescent current and robust performance in harsh electrical environments. Consider the thermal resistance characteristics if operating near maximum junction temperatures or driving significant loads.

Part Context

This part belongs to the ADA4098 family of precision amplifiers designed for industrial and automotive applications. The series includes single-channel (ADA4098-1) and dual-channel (ADA4098-2) variants. The BUJZ suffix indicates the specific 6-lead TSOT package and reel packaging format used for surface-mount assembly.

Replacement Considerations

Direct replacements within the same family include other ADA4098-1 variants with different grade or package options. Verify pin compatibility and electrical specifications before substituting with components from other manufacturers.
