ADA4097-1HUJZ-RL7

Overview

The ADA4097-1HUJZ-RL7 is a single-channel, precision operational amplifier manufactured by Analog Devices Inc. It features an ultrawide common-mode input range extending from −VS to +VS and beyond, supporting Over-The-Top operation up to 70 V. The device operates on a wide power supply voltage range of +3 V to +50 V with a typical quiescent current of 32.5 µA per channel. Key electrical specifications include a gain-bandwidth product of 130 kHz, a maximum input offset voltage of ±60 µV, and a minimum large-signal voltage gain of 120 dB. It provides robust protection against overdrive without phase reversal and includes a shutdown feature for low-power applications.

Feature Summary

• Ultrawide common-mode input range operating from negative supply up to 70 V above ground
• Low power consumption with typical supply current of 32.5 µA per channel
• High precision performance with low input offset voltage and drift
• Robust design tolerant to input overdrive conditions without phase reversal

Applications

• Industrial sensor 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 H-grade temperature rating (-55°C to +150°C) and the 6-lead TSOT package configuration when sourcing. Confirm that the ordering suffix corresponds to the reel packaging format required for automated assembly processes. Ensure compatibility with the intended supply voltage range and input common-mode requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring high-voltage signal processing with minimal power draw. The H-grade variant is suitable for extreme temperature environments. Consider the shutdown pin functionality if power management during idle states is critical. Verify that the 130 kHz bandwidth meets the dynamic response requirements of the target circuit.

Part Context

This part belongs to the ADA4097 family of robust, precision op amps designed for high-voltage, low-power applications. It complements the dual-channel ADA4097-2 variant. The series is engineered for industrial and automotive environments where reliability under abusive electrical conditions is paramount.

Replacement Considerations

Check for direct functional equivalents within the ADA4097 family or other Analog Devices high-voltage precision amplifiers. Verify pinout compatibility and thermal characteristics when substituting.
